钢框架梁端加强-螺栓全拼接节点的抗震性能有限元分析

摘要

In this thesis, seismic performance for beam Strengthening-Bolt spliced connection for steel moment frame were analyzed by using ABAQUS considering the geometric nonlinearity, material nonlinearity, contact nonlinearity, pre-tension of high strength bolts, Bauschinger effect and so on. The analyses results showed that Beam Strengthen - Bolt Spliced Connection can effectively make the relocation of the plastic hinge. The plastic rotation and energy dissipation capacity of beam Strengthening - Bolt spliced connection exhibited excellent.%本文应用有限元软件ABAQUS对钢框架梁端加强-螺栓全拼节点的抗震性能进行了分析,分析中考虑了几何非线性、材料非线性、接触非线性、高强螺栓的预拉力、包辛格效应等多种因素的影响,结果表明钢框架梁端加强-螺栓全拼节点可以很好的实现塑性铰的外移,具有良好的塑性转动能力和耗能能力.
