中文摘要：

运用通用有限元软件ANSYS建立三维有限元模型，对8个不同形式、不同构造的钢框架梁柱端板连接进行了非线性有限元分析（YEA），并与相应的试验结果进行了全面对比分析。比较结果表明：该文的有限元模型不但能够准确地分析计算各种类型和不同构造的钢框架梁柱端板连接节点的整体受力特性，包括承载力、弯矩．转角（M-φ）曲线、极限变形状态等，还能有效地分析计算节点及其组件的细部受力特性，包括高强度螺栓的预拉力，端板和柱翼缘之间的接触状态，以及节点域、端板、螺栓、端板加劲肋、节点域加劲肋等组件的受力状态，为进一步运用该模型对各种形式和构造的端板连接进行全面的有限元参数分析计算提供了正确性依据。同时，有限元分析还给出了螺栓预拉力引起的接触面预压力分布、荷载作用下接触面的摩擦力分布以及节点的主应力流分布等对于全面和深入理解端板连接节点受力特性非常有意义但是又难于通过试验进行测量的结果。

英文摘要：

Finite dement numerical models are developed by using the general-purpose finite element software, ANSYS, to simulate and analyze the mechanical behavior of beam-column end-plate connections with different types and details, and the corresponding tests are carried out to validate the finite element models. This finite element model＇s accuracy and efficiency are verified by a comprehensive comparison of the modeling and testing results. Hence it can be applied for further finite element parametric analysis on the end-plate connections with different types and details. Moreover, the finite element analysis provides some extra valuable results which are difficult to obtain in the tests, including the principal stress flow of the connections, the distributions of the pressure and the frictional force between the end-plate and column flange under the bolt pretension force and the joint moment.
