MODELLING OF STEEL-TO-CONCRETE END-PLATE CONNECTIONS UNDER MONOTONIC AND CYCLIC LOADING

Abstract

In this paper a model is introduced for the analysis of end-plate type steel-to-concrete connections under monotonic and cyclic loading. The developed model predicts the global response of the connection from the local behaviour of the 'tension' and 'compression' zone. The load-deformation relationships of the zones are analysed independently by two non-linear 2D FEM models. The calculated monotonic moment-rotation curves are presented and compared to the experimental results. The application of the model for cyclic analysis is also demonstrated. It is concluded that the relatively simple model provides good prediction for the behaviour of mixed connections under general loading conditions.
