摘要: 弦支筒壳结构是张拉整体概念与单层筒壳相结合而形成的一种新型预应力钢结构体系,该结构整体的可靠度是否满足规范要求是其能否形成合理有效结构体系的关键。基于概率理论和灵敏度分析方法,研究结构主要参数对弦支筒壳可靠度的影响,进而对各参数进行灵敏度分析,并拟合出可靠指标的计算公式,得到弦支筒壳结构适用性条件下的目标可靠度。Abstract: Supported barrel vault is a new type of prestressed structure,its origin is combining tensigrity system concept with single-layer lattice shell. It is necessary to analyze the reliability of the barrel vault structure and check up whether the value of reliability meets the requirements of codes,which is the key to forming a reasonable and effective system. Based on probability theory and sensitivity analysis method,this paper discusses the influences of main parameters on its reliability,carries out the sensitivity of all parameters,fits reliability index formula and finally obtains the target reliability index under applicability conditions.
