Numerical Analysis of the Behaviors of End-Plate Beam-to-Column Steel Joints Subjected to Cyclic Loading

摘要

This chapter presents the implementation of the modified Richard-Abbott model for the response of the extended end-plate composite joints subjected to cyclic loading. The combination of finite element models simulated in ABAQUS and the Richard-Abbott mathematical expression is the method to construct the hysteretic moment-rotation curves of the joint. The joint's parameters are found based upon the comparison between the analysis and the experimental results. After that, the behavior of the joint is analyzed subjected to various cyclical loads. The dissipated energy of the joint within a load cycle is estimated and discussed. Relationship between dissipated energy and stiffness degradation of a joint is found as the joint subjected to the arbitrary cyclic loading.
