1.???????? Introduction

Many? people,? directly? or? indirectly? involved? in? the? processes? of? design,? construction / de-construction,? or? management? of? buildings,? view? compliance? with? fire? safety? related? legislation? merely? as? an? awkward? problem? to? be? overcome,? with? minimum? cost? and? effort.??? Seldom? is? it? understood? that? the? fire? safety? objectives? which? underpin? those? provisions? are? limited? in? scope.??? In? the? case? of? current? national? legislation? in? the? European? Union,? for? example,? the? safety? of? a? building's? able-bodied? occupants? is? the? primary? concern ;?? not? only? is? safety? of? people? with? disabilities? inadequately? treated,? but? there? is? an? absence? of? any? coherent? technical? guidance? to? which? building? designers? can? make? reference.??? Typically,? also,? the? safety? of? firefighters? and? the? protection? of? property? are? merely? given? token? consideration.??? And? even? if? comprehensive? legislation? existed? at? national? level,? it? may? not? be? effectively? monitored? or? controlled? on? the? ground,? due? to? lack? of? political? will,? financial? resources,? or? any? number? of? other? reasons.?

The? following? text? presents? a? practical? introduction? to? fire? resistance? performance? in? buildings? -? in? a? format? which? is? intended? to? appeal? not? only? to? experts,? specialists,? practitioners,? regulators? and? controllers? in? the? fire? community? but,? additionally,? to? other? disciplines? working? in? the? mainstream? building? sector.?

Except? where? necessary,? every? attempt? has? been? made? in? the? text? to? ensure? that? terminology ?and? references? to? legislative? provisions? are? generic,? and? not? specific? to? any? individual? country,? its? legal? system,? or? national? body? of? standards.??? For? this? reason,? its? contents? constitute? a? common? basis? for? discussing? principles? and? defining? criteria? of? fire? resistance? performance? which? are? universally? applicable? and? relevant? at? all? stages? in? the? life? cycle? of? a? building,? whatever? the? nature? or? combination? of? materials? and? products? used.?

 

2.???????? What? is? a? Practical  Fire ?Engineering? Approach ?

To? examine,? and? think? through,? problems? associated? with? aspects? of? fire? safety? and? protection? in? buildings? -? in? this? case,? fire? resistance? performance? -? and? to? base? solutions? on? principles? of? reason,? common? sense,? science,? mainstream? engineering,? practicability? and? cost-effectiveness.?

The? benefits? offered? by? such? an? approach? include? ........?

  • the? provision? of? better,? and? more? reliable,? fire ?safety? and? protection? in? buildings ;?

  • more? cost-effective? safety? and? protection? measures,? and? more? options? with? regard? to? their? choice? and? specification ;?

  • better? communication? with? other? disciplines? involved? in? the? construction? sector.?

From? the? outset? of? this? approach,? it? must? be? clearly? understood? that? reality,? or? the? realistic? end? condition,? is? a? 'real'? fire? in? a? 'real'? building? which? is? occupied? by? 'real'? people,? a? regular? percentage? of? whom? will? be? limited? in? the? range? of? their? abilities,? i.e.? disabled,? at? the? time? of? any? fire? incident.?

Continuous? study? and? analysis,? therefore,? of? accurate? fire? investigation? reports? should? be? a? routine? practice? in? all? areas? of? the? professional? discipline? of? fire? safety? design / engineering.?



3.???????? Some? Fire? Related? Issues? in? a? Sustainable? 'Built? Environment'

Modern? architecture? has? evolved? dramatically? since? the? early? 1920's.??? Buildings? are? no? longer? designed? as? a? series? of? rooms? connected? by? a? circulation? route.??? Now? instead,? a? large? open? space? is? a? regular? feature? and,? in? many? instances,? spaces? will? be? linked? vertically? and/or? horizontally? through? a? major? extent? of? the? building.??? Loadbearing? construction,? i.e.? structure,? is? also? differentiated? from? non-loadbearing? construction,? i.e.? fabric,? to? a? far? greater? degree.??? Fire? safety? design? and? engineering? must? keep? pace? with? these? developments.?

Part? of? the? terrace? showing? the? independence? and? separate? treatment? of? the? cruciform? loadbearing? columns? and? the? non-loadbearing? walls.

?????????????? ? ?????????????

The? traditional? view? of? 'fire? resistance'? as? being? static,? robust? and? passive? must,? therefore,? not? only? be? extended? to? consider? a? complementary? relationship? with? 'active'? fire? protection? measures ,? it? must? be? stretched? to? embrace? the? concept? of? 'non-construction'?  [ see? definition? of? Sterile? Area (Fire)? in? Appendix? I? to? this? text ].?

With? a? growing? body? of? environmental? legislation,? at? European,? regional? and? local? levels? throughout? the? European? Union,? fire? safety? design? must? begin? to? address? some? of? the? following? issues,? which? relate? directly? to? fire? protection? in? buildings? ........?

  • requirements? for? far? higher? levels? of? reliable? fire? performance? in? order? to? reduce? and? control? adverse? impacts? on? the? environment? and? human? health? caused? by? fire ? ( see? the? more? developed? definition? of? Compartmentation? in? Appendix? I ) ;?

  • the? specification? of? environment-friendly? products,? components? and? building? assemblies,? etc. ;?

  • life? cycle? assessment / analysis / appraisal? of? specified? fire? protection? measures.?

Finally,? an? important? new? area? of? building? research? and? development? is? Sustainable? Construction? -? the? response,? in? built? form,? to? the? concept? of? 'sustainable? development'.??? This? concept,? i.e.? 'development? which? meets? the? needs? of? the? present? without? compromising? the? ability? of? future? generations? to? meet? their? own? needs',? has? recently? been? incorporated? in? the? primary? legislation? of? the? European? Union ( 1997 Amsterdam? Treaty ) .???? Fire? safety? design? has? an? important? contribution? to? make? to? this? global? goal? -? by? helping? to? preserve? the? 'natural? environment'? and,? as? a? core? value,? by? adopting? a? 'person-centred'? approach? to? fire? safety? in? the? 'built? environment'? and? effectively? protecting? human? health.?


See? the ??Fundamental? Matrix ??of? sustainability? performance? indicators.?

See? examples? of? completed? ?Indicators ,? which? are? directly? related? to? this? text.?

The? purpose? of? Construction? Related? Sustainability? Performance? Indicators? is? to? commence,? in? earnest,? the? practical? task? of? implementing? a? sustainable? approach? to? the? future? development? and? modification? of? the? 'built? environment'.??? The? Kyoto? Protocol? to? the? United? Nations? Framework? Convention? on? Climate? Change? has? made? this? a? short? term? legal? imperative? for? every? Member? State? of? the? E.U.?

 

4.???????? Fire? Safety? Design

Aware? of? the? limited? safety? objectives? in? building? legislation,? therefore,? and? following? careful? examination? of? the? nature? and? precise? location? of? a? particular? construction? project,? a? competent? person,? i.e.? a? fire? engineer,? should? start? by? identifying,? in? consultation? with? the? client / developer? and? other? members? of? the? design? team,? a? project? specific? range? of? 'indicated'? fire? safety? objectives .??? This? must? come? before? the? development? of? any? fire? safety? strategy.?

The? following? objectives? cover? a? wide? spectrum? of? concerns,? and? are? suggested? as? a? guide :?

(i)  protection? of? the? health? and? safety? of? all? building? users,? including? people? with? disabilities,? visitors? to? the? building? who? may? be? unfamiliar? with? its? layout,? and? contractors? or? product / service? suppliers? temporarily? engaged? in? work,? or? business? transactions,? on? the? premises ;?
(ii) protection? of? property,? including? the? building,? its? contents,? and? adjoining? or? adjacent? properties,? from? loss? or? damage ;
(iii) protection? of? the? health? and? safety? of? rescue? teams? and? firefighters ;?
(iv) the? buildability? of? necessary? re-construction? after? a? fire ;?
(v) protection? of? the? 'natural? environment'? from? adverse? or? harmful? impacts ;?
(vi) sustainability? of? the? 'built? environment'? -? including? the? proper? selection? and? life? cycle? assessment? ( see? EN ISO 14040 )? of? fire? safety? related? materials,? products,? components,? systems,? etc.,? fixed,? installed? or? incorporated? in? the? building.?

It? is ?only? after? the? objectives? have? been? clearly? stated,? that? a? cost-effective? fire? safety? strategy? may? be? designed? which? will? effectively? answer? the? requirements? of? the? client's? brief? and? the? project? performance? specification.? ??Once? completed,? this? strategy? becomes? the? basis? for? a? fire? defence? plan.?

A? fire? defence? plan? elaborates,? usually? in? the? form? of? a? manual? containing? drawings? and? text,? the? particular? fire? safety? strategy? which? has? been? adopted? for? a? specific? building.??? Under? no? circumstances? should? a? fire? defence? plan? contain? an? incomplete? strategy,? or? more? than? one? strategy.??? See? also? ISO 6790 :? ' Graphical? symbols? for? fire? protection? plans '.?

The ?style? and? presentation? of? a? fire? defence? plan? should? be? simple,? clear,? direct? and? precise ;?? and? it? should? contain,? at? least,? the? following? four? sections? ........?

( a ) a? statement? of? design? intent,? specifying? the? fire? safety? objectives? to? be? attained ;
( b ) a? listing? of? the? fire? protection? related? products,? materials,? assemblies? and? systems to? be? used? in? the? building ;?
( c ) proper? substantiation? of? stated? 'performance? in? use'? of? the ?items? listed? in? ( b )? above? ;
( d ) an? explanation? of? the? fire? safety? strategy,? indicating? how? the? various  listed? items? are to? be? used,? their? interaction? with? each? other? and? with? the? building.



5.???????? A? New? Language? of? Protection? from? Fire?

With? rising? standards? of? public? health? protection,? and? the? advent? of? larger? and? more? complex? building? types,? it? has? become? clear? that? the? old,? prescriptive? applications? of? fire? safety? design? 'rules? of? thumb'? are? inadequate.??? However,? to? create? the? innovative? concepts? which? are? necessary? to? develop? a? more? rational? approach? to? fire? safety? design? and? engineering,? standard? terminology? must? be? re-examined? in? order? to? clarify? and? make? more? immediate? its? meaning,? e.g.??? ........? ???????????????

Fire? Resistance : The? inherent? capability? of? a? building? assembly,? or? an element? of?construction,? to? resist? the? passage? of? heat, smoke? and? flame? for a specified time during? a? fire.

????????????? ?

'Real'? people? and? their? activities? in? buildings? are? very? important.??? It? is? no? longer? the? case? that? all? building? occupants? must / should / can? be? evacuated? in? 21/2 minutes .??? In? the? different? situations? of? hospitals? and? very? large? complex? building? types,? for? example,? but? also? security? establishments,? certain? research? laboratories,? and? organizations? committed? to? 'service? quality',? e.g.? hotels? -? it? is? neither? practicable,? nor? desirable,? that? a? building? be? entirely? evacuated? at? once.??? Building? occupants? must? be? able? to? move? confidently,? or? be? moved,? to?? 'places? of? relative? safety' ,? or? they? may? have? to? be? fully? protected? in? place.??? Higher,? more? reliable? levels? of? fire? performance? are? demanded.?

 


6.???????? Structural Design for Fire

As? our? understanding? of? fire? behaviour? in? 'real'? buildings? grows,? greater? attention? is? being? paid? to? structural? reliability,? and? the? design? of? structural? systems? for? performance? in? fire? conditions? ........? ???????????????

Structural? Reliability :
(ISO 2394)
The? ability? of? a? structural? system? to? fulfil? its? designpurpose,? for? some? specified? time,? under? the? actual environmental? conditions? encountered? in? a? building.?



In? addition,? particular? focus? is? being? drawn? to? the? complex? relationship? between? structure? and? non-structural? infill,? or? fabric,? which? typically? in? modern? buildings? is? lightweight? and? non-loadbearing.??? Under ?fire? conditions,? this? relationship? becomes? an? intense? interaction? which? impacts? on? the? efficient? fire? performance,? i.e.? serviceability,? of? both.




 

 

 

 

 

 

 


Figure 2????? The? complex? relationship? between? Structure? and? Fabric? in? a? fire? situation? must? be? studied? and? researched.????? See? a? more? developed? sketch? drawing.?



In? general? terms,? the? reliability? of? a? building? structure,? i.e.? the? loadbearing? construction,? is? its? ability? to? fulfil? its? architectural? design? purpose? for? some? specified? time? under? the? actual? environmental? conditions? encountered? in? the? building.??? The? fire? performance? of? a? whole? structure,? or? part? of? it?? -?? the? principal? concern? of? this? text? -? may? be? more? precisely? specified? in? engineering? terms? by? reference? to? a? defined? set? of? limit? states? beyond? which? the? structure? no? longer? satisfies? the? project's? architectural? and? fire? safety? design? requirements.?

Those? limit? states? may? be? divided? into? the? following? two? categories :-?

(a) ultimate? limit? states,? which? in? structural? design? for? ambient? conditions? correspond? to? maximum? load-bearing? capacity? but,? typically,? in? design? for? fire? still? correspond ?to? the? 'near-maximum'? loadbearing? capacity? intended? to? avoid? damage? to? laboratory? furnaces? caused? by? test? specimen? collapse? -? see? definition? of? horizontal? loadbearing? element? 'failure'? in? a? sample? test? standard,? e.g.? BS 476 : Part 20? ( Clause? 10.2.3 )? ........

                ?



and? an? interesting? note? in? Appendix A,? Paragraph 10,? of? the? same? standard? concerning
loadbearing? vertical? elements? ........?



(b) serviceability? limit? states,? which? in? 'ambient'? design? correspond? to? criteria? governing? function? related? use? but,? unfortunately,? in? design? for? fire? are? not? yet? properly? recognized.?

 

Ultimate? limit? states? in? fire? engineering? should? instead? be? equally? understood? to? mean,? for? example? ........?

  • rupture? of? critical? sections? of? the? structure? caused? by? exceeding? the? ultimate? strength? (in? some? cases? reduced? by? repeated? loading) ,? or? the? ultimate? deformation? of? the? material ;?

  • transformation? of? the ?structure? into? a? mechanism? (collapse) ;
    ?
  • loss? of? stability? (buckling,? etc.) .?

 

Serviceability? limit? states? in? fire? engineering,? which? are? of? more? immediate? and? direct? relevance? to? the? protection? of? both? human? health? and? property,? and? necessary? re-construction? after? a? fire,? would? correspond? to,? for? example? ........?

  • deformations? which? affect? the? efficient? use,? i.e.? the? fire? performance,? or? appearance? of? structural? or? non-structural? elements ;

  • local? damage? (including? spalling? and? cracking)? which? reduces? the? durability? of? a? structure? or? affects? the? efficiency? or? appearance? of? structural? or? non-structural? elements.?

 

To? control? fire? serviceability? limit? states? by? design,? therefore,? it? is? necessary? to? use? one? or? more? constraints? which? describe? acceptable? deformations? (+/-deflection,? expansion,? distortion,? etc.) ,? accelerations,? crack? widths,? spalling,? etc.?????See? some? comments? and? questions.?


Now? refer? back? to? the? definition? of? 'fire? resistance'? in? B.S. 476 : Part 20? ........?????

Fire? Resistance : The? ability? of? an? element? of? building? construction to? withstand? exposure? to? a? standard? temperature/time and? pressure? regime? without? loss? of? its? fire? separating function? or? loadbearing? function? or? both? for? a? given? time.?

This? definition? does? not? attempt? to? establish? a? relationship? with? 'real'? fire? behaviour? in? a? 'real'? building.??? A? standard? fire? test,? on? the? other? hand,? involving? exposure? of? a? test? specimen? or? prototype? to? 'test? fire'? conditions,? will? give? only? a? limited? indication? of :-?

(i) the? likely? performance? of? a? particular? product,? material? or? component? when? exposed? to? 'real? fire'? conditions ;?
(ii) the? suitability? of? a? product,? material? or? component? for? a? particular? end? use.?



Furthermore,? there? is? a? fundamental? mismatch? here? between? the ?concepts? of?? fire? separation? ........

' ensuring? that? a? fire,? or? any? of? its? constituent? parts,? i.e.? heat,? smoke? or? flame,
cannot? move? or? spread? from? Point? A? in? a? building? to? Point? B '?

and?? structural? reliability ?in? fire ,? which? has? already? been? defined ;?? both? concepts? are? not? even? complementary.??? A? single? definition? cannot? handle? this? overload ;?? it? makes? no? sense? and,? as? a? result,? its? meaning? for? the? everyday? practitioner? in? the? building? industry? is? obscured? and? lost.?





7.???????? Reliability? of? Fire? Performance? in? Buildings

An? issue? which? is? becoming? increasingly? critical,? in? striving? to? rationalize,? analyse? (as? distinct? from? assess),? improve? and ?optimize? fire? performance? in? buildings,? is? that? of? 'reliability.??? Can? we? confidently? depend? on? an? element? of? construction,? an? installed? product,? or? a? building? system? to? perform? as? expected? whenever? a? fire? might? occur? -? at? any? stage? in? the? life? cycle? of? that? building ????? Design,? construction? workmanship,? maintenance,? 'real'? intended? use,? and? an? economically? reasonable? working? life? for? the? building,? are? important? factors? which? must? be? considered? by? the? fire? safety? designer? as? a? member? of? a? project's? design? and? construction? teams.?

The? following? are? some? variables? which? influence? performance? reliability,? and? should? be? taken? into? account? by? a? competent? person? in? the? detailed? development? of? a? fire? safety? strategy :?

(i) Precision? of? fire? test? methods?? -?? is? a? fire? performance? rating? of?? '60 minutes'?? in? one? test? laboratory? equivalent? to? a? similar? rating? in? another? laboratory ??
(ii) Installation? alterations? on? site.??? Have? any? changes? been? made? to? a? product,? as? originally? fire? tested ????? Have? any? of? the? fixing? details? been? altered ????? Have? any? changes? been? made? on? site? in? order? to? ensure? a? proper? fit ????? If? assemblies? do? not? fit,? how? have? resulting? larger? gaps? and? clearances? been? handled? by? the? building? contractor ?
(iii) Workmanship?? -?? is? it? good,? bad? or? ugly ????? Has? it? been? competently? supervised,? or? not ??
(iv) Has? there? been? any? interference? with? an? installed? product?? -?? by? other? trades? at? later? stages? in? the? construction? process ?
(v) Servicing? and? maintenance?? -?? will? any? be? carried? out,? by? somebody? competent? to? do? so ?
(vi) What? information? do? you? have? about? the? management? system,? personnel,? and? reporting? relationships? in? a? building ????? Are? they? efficient / competent / effective ?
(vii) Improper? use? and? abuse? by? the? building's? occupants?? -?? for? example,? would? you? ever? expect? to? find? a? situation? like? that? shown? below ??

8.???????? Proper? Substantiation? of? Fire? 'Performance? in? Use'

Within? the? European? Union,? products,? components,? fittings,? items? of? equipment,? systems,? etc.,? used? in? the? construction? of? buildings? must? be? shown? to? be? 'fit? for? their? intended? use' ,? at? the? location? and? under? the? conditions? in? which? they? are? to? be? used? ........?

This? requirement? is? expressed? in? the? Building? Regulations? for? England? and? Wales,? as? Regulation 7 :-?

Figure 4????? Regulation 7? of? the? Building? Regulations? for? England? and? Wales.?

 

Appendix A? of? Approved? Document? B? for? England? and? Wales? provides? additional? guidance? with? regard? to? the? performance? of? fire? protection? related? products,? components,? systems,? etc.??? This? information? must? be? read? as? being? related,? and? subordinate,? to? Regulation 7.??? Once? the? boundary? of? application? of? a? Fire? Test? Report? is? exceeded,? however,? Appendix A? is? not? clear? what? an? 'Assessment'? is,? or? who? exactly? is? the? 'competent? person'? to? produce? such? documentation.?
