Simplified finite element analysis of bolted T-stub connection components

摘要

In order to predict the T-stub behaviour, simplified theoretical models are provided by Eurocode 3 that allow to evaluate the T-stub stiffness and strength. Conversely, there are no codified rules to predict the plastic deformation capacity. Therefore, the prediction of the T-stub ductility is still an open issue in the connection modelling. Even though theoretical models are very important in order to recognise the parameters that govern the stiffness, resistance and ductility of bolted T-stubs, they cannot always be applied with confidence, because of the simplifying assumptions usually made for gaining closed form solutions. Therefore, the information coming from simplified theoretical models needs to be integrated with that obtained either by experimental results or by means of finite element simulations.
