提出了一种将蒙特卡罗模拟法与响应面法相结合的混合模拟法,并考虑结构体系在强度、刚度和稳定性联合失效模式下进行可靠性分析.以巨型海上浮式起重机结构体系为例,计算得到其结构体系在静力作用状态下的联合失效概率和可靠性指标,证明了文中所述方法的可靠性和高效性.%This paper introduces a new kind of hybrid simulation method which combines Monte Carlo simulation approach and response surface method together and performs reliability analysis of crane structural system for the coalition mode of strength, stiffness and stability. With the structural system of giant floating crane as an example, the union failure rate and reliability index of its structural system under static condition are worked out in this paper, which proves the reliability and efficiency of the mentioned method.
