Abstract:

Human safety and adequate performance of buildings after extreme hazards are key to the context of resilient cities. Resilience-based design procedure can be developed using probabilistic approaches, considering uncertainties in the occurrence of events and behavior of structures under the hazard. Fire after earthquake and fire by itself are major hazards with possible intense consequences. As part of developing a framework to evaluate fire resilience of steel structural systems, this research provides probabilistic models for fire load density and properties of materials at elevated temperatures. The developed models are then used to evaluate reliability of structural components as well as the structural system under post earthquake fire. The probabilistic analysis provides a more realistic performance of the structure and permits informed decisions to be made for design under fire.
