摘　　要：利用有限元数值分析软件ANSYS建立半刚性端板节点模型进行非线性有限元分析.在建立模型和计算分析过程中考虑了弹塑性、大变形和接触问题,有限元分析结果与试验结果吻合良好.根据梁腹板、端板厚度和螺栓对端板强度影响,对传统计算端板强度的T形件方法进行了修正.分析结果表明:根据端板的破坏模式应采用相应修正系数来考虑上述因素的影响.该方法对端板强度的设计有一定的参考价值.The behaviors of bolted extended end plate connections were analyzed by using the finite dement software ANSYS. The analytical models took into account material no. nlinearifies, large displacements and geometrical discontinuities. The analysis has shown that the analytical results match well with experimental results. The traditional T-STUB member calculation method was modified, considering the effects of the bolt and the thickness of the beam web and the end plate on the strength of the end plate. The analytical results have indicated that different failure modes of end-plate have the corresponding correction coeffidents. This method has some reference value for the design of end-plate.
