Review of Indonesian Standard for Concrete Building Subjected to Fire

Fire safety engineering design of concrete structures in Indonesia is principally based on individual member from results of isolated beams, columns, and slabs tested in small furnaces. However, researchers identify that the behaviour of individual isolated members is significantly different from behaviour of complete structure connected together when subjected to fire. Although the current guidance is conservative when the entire building performance is considered, it should be noted that the beneficial and detrimental effects in complete structures should be taken into account. The effect of concrete spalling in fire has also not been enclosed sufficiently in the code. It should also be noted that the reduction of steel reinforcement cover could generate premature collapse of the structures. Since designers and engineers need to understand the behaviour of entire structure in fire, developing engineering guidance based on realistic structural behaviour is essential.
