Modelling of HSS endplate connections Achievements and perspectives: abstract
conference paper
This paper deals with the behaviour of high strength steel (HSS) endplate connections at ambient temperature using the finite element software ABAQUS. The detailed FE model is complicated, considering material and geometric non-linear effects, large deformations and contact interactions. The big challenge of modelling contact interactions has been solved successfully. Validation against experimental results shows that the proposed model can reproduce the behaviour of mild steel endplate connections at ambient temperature with reasonable accuracy. Using HSS instead of mild steel as endplate material, this model is able to predict the performances of HSS endplate connections at ambient temperature. By a parametric study, it is found that a thinner HSS endplate enhances ductility of the connection at ambient temperature, and helps the connection to achieve the same load-bearing capacity as with mild steel endplate connection. This finding opens perspectives for further investigation of improving the robustness of endplate connections in fire. © 2010 Taylor & Francis Group, London.
