Finite element modelling of cyclic behaviour of cold-formed steel bolted moment-resisting connections

This paper investigates the accuracy of new finite element modelling approaches to predict the behaviour of bolted moment-connections between cold-formed steel members,formed by using brackets bolted to the webs of the section,under low cycle fatigue. abaqus software is used as a modelling platform. such joints are used for portal frames and potentially have good seismic resisting capabilities,which is important for construction in developing countries. the modelling implications of a two-dimensional beam element model,a three-dimensional shell element model and a three-dimensional solid element model are reported. quantitative and qualitative results indicate that the three-dimensional quadratic s8r shell element model most accurately predicts the hysteretic behaviour and energy dissipation capacity of the connection when compared to the test results. © penerbit universiti sains malaysia,2016.
