摘要: 为提高大型钢结构系统可靠性分析方法的效率和精度,提出约界参数CAP(Control ambit parameter)的概念,通过对立体车库大型钢结构系统的有限元参数化建模、主要失效模式的算法研究,建立了该失效模式的安全余量方程。在此基础上,编制分析计算软件并对立体车库钢结构可靠性进行定量计算,结合算例分析其在大型钢结构系统可靠性中对失效准则、失效模式和系统失效概率的影响,得出应根据结构规模和特征选取适合的CAP值才能保证真正反映系统实际失效概率。

关键词: 结构系统可靠性, 失效模式, 失效准则, 约界参数CAP

Abstract: In order to advance efficiency precision of reliability analysis for large type steel structure system, the conception of control ambit parameter (CAP) is put forward. Through finite element parameterization modeling and calculation method research of main failure mode on steel structure of the Space-Parking System, the safety equation is set up. Based on analysis calculating software workout and calculating of reliability on steel structure of the Space-Parking System,the influence on failure mode, failure rule and reliability of system of large type steel structure is analyzed.

Key words: Failure rule, Control ambit parameter (CAP), Failure mode, Reliability of structure system
