Numerical Analysis of High Strength Steel Endplate Connections at Ambient and Elevated Temperatures
This paper deals with the behaviour of high strength steel (HSS) endplate connections at ambient and elevated temperatures using ABAQUS. The detailed FE model considers material and geometric non-linear effects, large deformations and contact interactions. This paper highlights the main challenges in modelling endplate connections. Validation against experimental results shows that the proposed FE model can reproduce the behaviour of mild steel endplate connections with reasonable accuracy. Using HSS instead of mild steel as endplate material, this model is able to predict the performances of HSS endplate connections both at ambient temperature and under fire condition. By a parametric study, it is found that a thinner HSS endplate enhances the ductility of connection both at normal condition and under fire condition, and achieves the same load-bearing capacity with mild steel endplate connection. This finding is promising for further investigations on improving the robustness of endplate connections in fire.
