Abstract

In this paper a simplified robust 2-noded connection element has been developed for modelling the flexible end-plate connections at elevated temperatures. In this model, the two stage behaviours of flexible end-plate connection are considered. The model has the advantages of both the simple and component-based models. It is computationally efficient and has very good numerical stability under static solver conditions. A total of 14 tests are used to validate the model, demonstrating that this new connection model has the capability to accurately predict the behaviour of the flexible end-plate connections at elevated temperatures. The model can be used to simulate the flexible end-plate connections in real performance-based fire resistance design of steel-framed composite buildings.
