[ 摘要] 运用 ANSYS 对 8 个不同形式、不同构造的钢框架梁柱螺栓端板连接进行了非线性有限元分析。
采用 PSMESH 在高强度螺栓中建立预拉面,并施加预拉力;通过创建接触对模拟端板和柱翼缘
之间的接触。弯矩-转角曲线、弯矩-剪切转角曲线与实验的对比说明了,运用 ANSYS 软件能
够很好地分析计算各种形式、各种构造的钢结构梁柱螺栓端板连接,为下一步进行大量的梁柱端
板连接有限元计算提供了正确性依据。而这必将大大减少端板连接实验研究工作量,降低成本,
节约时间,同时,还能够获得目前试验中不能直接测量得到的结果。

[ Abstract ] The large-scale general-purpose finite element code ANSYS is adopted to analyze 8
structural steel beam-column end-plate connections of various types and details. mand
PSMESH is used to create pretension sections in high strength bolts, by which pretension
forces are applied. And the contact between the end-plate and column flange is simulated by
creating a contact pairs. parison to tests results on the moment-rotation and

moment-shear rotation curves, it has been verified that ANSYS can simulate and analyze all
kinds of end-plate connections with different details, which has provided the validity of a large
number of further finite element analysis on beam-column end-plate connections. This will
reduce the ex
