摘要
在杆系结构可靠性分析中,求取临界失效模式是一个主要课题。本文提出了可考虑轴向力和弯矩耦合效应的可靠性分析方法,它采用比例加载乘子λ这一物理意义明瞭的参数来作为判别临界机构的准则,算例表明了此方法的可行性、有效性。
In the structural reliability analysis of frames ,it is a primary subject to identify the critical failure modes. This paper l rovides the reliability analysis method which can consider the couple of axial force and bending moment. It uses proportionally load multiplier with the clear physical meaning as a criterion of identifying the critical mechanisms. The results show that the method is feasible and effective.
