This paper examines the fire smoke hazards of commercial - multi-function buildings known asRumah Toko or ?Ruko" The fire simulation was carried out using the NIST Fire Dynamic Simulators(FDS) model. The input for the model was taken from a typical design and sizes of this building built inIndonesian cities. On the basis of a set fire, two (2) design scenarios have been analyzed, i.e. thetraditional design and an improved design. The results of this work show that in the ordinary design ofthe Ruko building, smoke production during a fire can overcome the occupants in relatively short periodof time. Meanwhile the improved design by means of installing smoke shaft systems can improve theventing capacity of the building. On the basis of smoke density level, the margin of safety for evacuationefforts is extended from 160 s to more than 400 s by the use of smoke shaft systems. |
