摘　　要：利用有限元软件ANSYS对端板型半刚性节点进行了弹塑性计算,分析了端板厚度对端板型节点中螺栓内力和变形的影响。螺栓内力及变形与节点所用端板厚度有关,并不完全符合传统的设计方法,从而提供了一些在端板型节点设计时值得思考的问题。The elastoplastic calculation on the semi-rigid joints with end-plate was carried out by using the finite elements software ANSYS,and the effects of the end-plate＇s thickness on the internal force and the deformation of bolts in the end-plated joints were analyzed.The internal force and the deformation of bolts are relative to the end-plate＇s thickness at joints,which do not completely accord with the traditional design methods.Therefore,some problems to be worth thinking will be provided for the design of the end-plated joints.
