| 摘 要： | 根据《型钢混凝土组合结构技术规程》(JGJ 138—2001)给出的型钢混凝土节点抗剪承载力设计公式,用Monte-Carlo法对型钢混凝土节点抗剪承载力的可靠指标口进行计算。Matlab的数值计算功能解决了Monte- Carlo法直接抽样的困难,并通过一算例定量分析了荷载效应比、混凝土强度等级和节点核心区配箍率等变化对节点抗剪承载力的可靠指标β的影响。

| Abstract: | The Technical Specification for Steel Reinforced Concrete Composite Structures(JGJ 138—2001)gives formula to calculate shear bearing capacity of the steel reinforced concrete joints. The Monte-Carlo method is used to analyze the reliability of the formula. The numerical calculation function of matlab solves the difficulty of direct sampling, and through an example quantitatively analyzed the reliability index of the design formula and the relations among different ratios of load effect, strength of concrete and stirrup reinforcement ratio and so on. |
