摘要
推导了半刚性连接单元的刚度矩阵,提出半刚性连接单元受任意分布力作用时的节点荷载的一种等效方法,依节点连接弯矩-转角曲线的特性给出了合适的离散公式,再根据离散控制系统理论编制了能考虑节点连接非线性的半刚性连接钢框架计算程序;最后,分别运用编制的计算程序和有限元软件ANSYS对典型题例进行计算分析,通过比较计算结果得出了半刚性节点连接对钢框架力学行为及变形性能的影响,进而验证了程序的准确性。
The stiffne＆s matrix of semi-rigid element was deduced. An equivalent node-load method for semi-rigid element with arbitrary distributing force was presented. And according to the characteristics of curve of moment-rotation, a proper dispersing formulas was provided. Then, based on the Distributed Control System （DCS）, the program which had considered the nonlinear factor for steel frames with semi-rigid connections was compiled. Finally, the program and finite element software ANSYS were employed separately to analyze the typical sample. By comparing the results, the mechanical and deformable behaviors for the steel frame with semi-rigid connections were obtained, and then the correctness of calculation program has been validated.
