摘要
结构在施工期可靠度的分析对于保证施工安全具有重要意义。由于在施工期间,结构是一个时变结构,结构抗力是一个随机过程,荷载也与使用期的不同,所以有必要研究施工期间结构的可靠度。本文结合混凝土结构在施工期的特点,建立了施工期结构可靠度的全随机模型,分析了考虑抗力随时间变化的模拟计算原理并进行了模拟计算。结果表明,本文的计算方法可以用来对精确解进行校核或验证近似解析解。
Reliability analyse of the structure during construction period that is very importance to guaranty contruction safety. It is necessary to study the reliability of the structure during the construction because the structure is a time-varying system and the variable loads are random processes about time with particular characteristics different with the use period, random model of the structural reliability during construction period is established. Simulation principle of the structural resistance varying with time is analysed. And simulate calculation is gotten accord- ing to the characteristics of concrete structures. The result of the anslysis shows this method can be used to verify or validate the relative precision approximate analytic solution.
