Abstract
This paper presents the behaviour of the composite frame with concrete-filled square hollow section (SHS) columns to steel beam. Finite element modeling (FEM) was developed to carry out the behaviour of composite frames under a constant axial load on columns and a lateral cyclic load on the frame. Accurate material and geometrical nonlinear for confined concrete and steel were considered in the analysis. The finite element program ABAQUS was adopted. A damage plastic model for concrete and elasto-plastic model for steel were used respectively. Six composite frame tests were carried out to verify the FE model. Each test frame specimen consisted of two concrete-filled SHS columns and a steel beam to represent an interior frame in a building. The results obtained from the finite element model were verified against those obtained from the experimental results.
