| 摘 要： | 基于力法方程推导得出梁柱节点刚度对半刚性连接钢框架整体力学性能的影响,确定了当框架承受均布荷载时,节点刚度与框架内力、变形的关系,并得到能使框架内力和变形处于最合理分配时的节点刚度。利用通用有限元软件ANSYS模拟计算了框架承受静荷载和动荷载时的内力和变形,计算结果验证了理论推导的正确性。

| Abstract: | Based on the equation of force method,the influence of joint stiffness on the mechanical behaviors of steel frame with semi-rigid connections was obtained.When the structures bear uniform loadings,the relationships of the joint stiffness with the internal forces,the joint stiffness with the structure deform were gained.The joint stiffness which would make the structure internal forces and deformation distributed properly was determined.Then the finite element software ANSYS was employed to compute the internal forces and deformation of the frames which bear static and dynamic loadings separately.And the correctness of theoretical deduction above has been validated. |
