摘 要:根据110根轻骨料混凝土受弯构件受剪承载力实验数据,并应用GB/T 50283—1999《公路工程结构可靠度设计统一标准》和GBJ 68—84《建筑结构设计统一标准》提供的结构可靠度分析的一次二阶矩法,对JGJ 12—2006《轻骨料混凝土结构技术规程》和CECS202:2006《轻骨料混凝土桥梁技术规程》中轻骨料混凝土受弯构件受剪承载力的计算公式进行研究与可靠度分析。研究结果表明, JGJ 12—2006中受剪承载力计算公式的可靠指标为3.745,而CECS202:2006中受剪承载力计算公式的可靠指标为4.576。
Abstract:Based on the experimental results of 110 lightweight aggregate concrete flexural members, study and reliability analysis are made on the calculation formulae of shearing capacity of lightweight aggregate concrete flexural members in “Technical specification for lightweight aggregate concrete structures” (JGJ 12—2006) and “Technical specification for lightweight aggregate concrete bridges”(CECS 202:2006) by the second moment of first order method recommended in “Unified Standard for reliability design of highway engineering structures”(GB/T 50283—1999)and “Unified Standard for design of building structures”(GBJ 68—84).The results show that reliability index of the calculation formula of shearing capacity is 3.745 in JGJ 12—2006, but is 4.576 in CECS202:2006.
