Finite element modeling for the progressive collapse analysis of steel stiffened-plate structures in fires

This paper is a sequel to the authors’ articles which provided test data on progressive collapse of full-scale steel stiffened-plate structures without and with passive fire protection (PFP) under lateral patch loading in fires [1,2]. presents new computational models for analyses heat transfer fire-induced behaviour stiffened plate or PFP. For this purpose, transient thermal elastic-plastic large-deformation finite element were formulated. The developed validated by comparison data. novelty associated procedure analysis critical contribution safety engineering plated structures.
