Abstract

The paper discusses the frame analysis using 3D finite element models to investigate the influence of partially restrained (PR) connections with high strength steel on steel building structure frameworks. Rigorous application of finite element computing package ANSYS 10.0 has been used to analyze the structural behaviour of the frames. The boundary restraints are represented as a combination of linear and rotational springs, where the springs stiffness are derived based on the assumption of semi-rigid beam-to-column connections. The strain softening is considered to analyse the beams during deformation. The proposed models are compared using a two-dimensional (2D) frame analysis. It has been demonstrated that simplified portal frame analysis with non linear spring element give significant role to predict the behaviour of PR connection due to strain softening effect up to complete failure. From these models it will be possible to establish new design methods for frame design utilising the strength and stiffness of PR connections with high strength steel utilising beam strain softening.
