| Summary: | 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 threedimensional quadratic S8R shell element model most accurately predicts the hysteretic
behaviour and energy dissipation capacity of the connection when compared to the test
results. |
