通过节点柔度对半刚性连接框架可靠性的影响构造半刚性连接模型,分析了半刚性连接点对框架有限元的影响.把构件抗力和荷载效应看作随机变量,对折减刚度矩阵和等效虚拟荷载进行分析,用蒙特卡罗模拟法来估计框架系统的失效概率,对非线性半刚性、线性半刚性、完全铰接三种状态进行分析比较,表明半刚性连接点行为在整个钢框架系统可靠性计算中起到重要作用,因此当对钢框架进行可靠性分析时不能忽略半刚性连接体的影响.
The semi-rigid connection model is constructed by the influence of joint flexibility on the reliability of semi-rigid connection frame, the influence of semi-rigid connection point on the finite element of frame is analyzed, and the component resistance and load effect are regarded as random variables. The reduced stiffness matrix and equivalent The virtual load is analyzed. The Monte Carlo simulation method is used to estimate the failure probability of the frame system. The analysis and comparison of the three states of nonlinear semi-rigid, linear semi-rigid and complete articulation shows that the behavior of semi-rigid joints is reliable in the entire steel frame system Sex calculations play an important role, so you can not ignore the effects of semi-rigid connectors when performing reliability analyzes on steel frames.
