AN OPENSEES-BASED INTEGRATED TOOL FOR MODELLING STRUCTURES IN REALISTIC DESIGN FIRES

摘要

This paper describes the development of OpenSees on integrating the heat transfer and thermo-mechanical analyzes for modelling structures in fires.The Heat transfer to a composite beam subjected to localized fire is investigated within OpenSees, and the robustness of adopting two dimensional approximation of heat transfer analysis has been reviewed.Non-uniform thermal action is implemented in OpenSees and its performance having been verified.
