Fire and collapse modelling of a precast concrete hall

A large fire occurred in a factory manufacturing personal care products. The facility was extensively damaged. The response of the structure and fire results in the building are discussed. The presented analysis includes numerical modelling of the thermal environment within the compartment of the fire origin and subsequently a finite element analysis of heat transfer into the structural elements as well as the analysis of the mechanical response of the whole building structure. The aim of the study was to understand the principal aspects of the response of the main load bearing structure (including post-tensioned girder elements) in a real fire.
