| 摘 要： | 为了解顶底角钢半刚性连接的抗弯特性,利用简化的斜率-位移方程推导了半刚性连接初始刚度的计算公式,根据角钢的塑性特性计算了半刚性连接的极限弯矩,进行了两类柱弱轴顶底角钢半刚性连接的抗弯试验,并利用三参数幂函数模型模拟了所研究的半刚性连接的弯矩-转角曲线.结果表明,模拟结果与试验结果吻合很好,文中提出的新型连接形式具有很好的抗弯能力.

| Abstract: | In order to investigate the flexural resistance of semi-rigid connections,a formula was deduced based on the simplified slope-displacement equation to calculate the initial stiffness of the semi-rigid connection with top-and-seat angles.The ultimate moment of the connection was then obtained according to the plastic characteristics of the angle.Moreover,the flexural behaviors of two types of semi-rigid connections of column minor axis with top-and-seat angles were experimentally discussed.The moment-rotation characteristics of the above-mentioned connections were finally simulated by using the three-parameter power model.The results show that the simulated results accord well with the experimental ones,and that the new connection form designed in this research possesses good moment capacity. |
