钢筋混凝土构件裂缝和挠度可靠度灵敏度分析

The reliability and sensitivity analysis on the crack and flexibility of steel reinforced concrete component

应用可靠度灵敏度分析方法,针对钢筋混凝土梁的两种正常使用极限状态,分别计算了在不同的荷载比和配筋率情况下,其正常使用可靠度指标对随机变量分布参数和极限状态方程参数的敏感度系数,从而总结出影响裂缝宽度和挠度的敏感性因素。

Using the reliability and sensitivity analysis method and aiming at the two normal used limiting state of steel reinforced concrete beam, it calculates the index of normal used reliability to the distribution parameter of random variable and the sensitivity coefficient in different load ration and ratio of reinforcement, and sums up the factors of affecting the width and flexibility of the cracks.
