具有中介状态砌体结构的可靠性分析
|
摘要
实际工程中,结构通常应具有“安全-中介-失效”工作模式,这里的“中介”即为“故障”,是系统(或结构)既不能完全发挥其应有的全部功能,又不是完全不能发挥其全部功能,是一种具有不确定性的中介状态.应用王光远先生所提出的具有“安全-中介-失效”三级工作模式的结构的可靠性分析方法,利用设计基准期50年内结构底部剪力、层剪力(或层弯矩)等的概率分布为极值Ⅱ型的特点,建立了具有中介状态的砌体结构可靠性向量的计算方法.分析一实际的砌体结构,应用此方法求出结构在地震作用下对应的安全概率(可靠度)、中介概率PM和失效概率PF,它们联合起来构成可靠性向量[PR,PM,PF].
In actual engineering,structures commonly work with a 3-level working mode of "safety,intermediate,failure".It is difficult to apply the traditional fuzzy reliability theory to practical engineering because some fuzzy work states are introduced,method of dealing factors detailed continuously,analysis model complicated more and more,and calculation program too scholastic.Calculation method for masonry structure with intermediate state is put forward according to probability model and its statistical parameter for seismic load in the paper.Results of analysis should be safety probability(reliability),intermediate probability and failure probability.These factors combine to form the reliability vector.
