RELIABILITY EVALUATION OF RESIDENTIAL BUILDINGS IN FIRE

摘要

Performance-based design is becoming more widespread in structural fire engineering, but it is still inconsistent with the design of other types of hazards.This study works on extending the reliability evaluation framework to consider the system level structural reliability under fire by using Latin Hypercube sampling.A computational zone model was used to simulate the realistic fire scenario with the help of a fire spread model based on the NFPA's latest fire incident report system.The temperatures of structural members were obtained by a heat transfer simulation, and a 3D frame model was created in Abaqus to predict the structural responses.This study demonstrates that the structure in a realistic multicompartment fire could have different failure modes in comparison to the single compartment fire, and the more realistic fires may cause more severe structural damages.
