Description

Steel joints subjected to cyclic loading whereby the amplitude of the applied forces exceeds the yield strain of one or more of the relevant connection components usually exhibit degradation of its moment-rotation response that eventually leads to failure of the joint. Depending on the actual design of end-plate beam-to-column steel joints, the cyclic response may present slippage. It is the purpose of the present paper to (i) discuss the various hysteretic models available to model steel joints under cyclic loading; (ii) describe a numerical implementation of two such models, with and without slippage, and (iii) compare the cyclic response of two distinct joints (with and without slippage), and (iv) based on a selected test case, assess the influence of slippage on global behaviour of the structure.
