Finite element modelling of composite end-plate connection under elevated temperature

Abstract

A three-dimensional finite element thermal model is proposed to predict the temperature histories of various components of composite connections under fires. The model was carefully calibrated against a series of standard fire tests. Temperature histories, both within connections and in composite sections, are compared and calibrated. A two-dimensional finite element mechanical model is adopted and calibrated to predict the structural response of composite connections at elevated temperatures. Both of the proposed models are verified to be efficient tools for integrated analysis and design of composite end-plate connections under various fire scenarios. © Institution of Engineers Australia, 2010.
