摘要
采用蒙特卡罗（Monte—Carlo）方法，对按现行规范中组合梁负弯矩区混凝土板裂缝宽度的计算公式进行可靠度分析，研究了不同荷载比值、不同配筋率及不同材料强度等级对组合梁可靠度的影响，得出最大裂缝宽度公式的可靠指标的变化范围。
The analysis of reliability of equation of the crack width of concrete slab in the hogging moment region of composite beam in the current codes is conducted by using Monte-Carlo methods. The effects of different load ratio, ratio of reinforcement, strength level of material on reliability of composite beam is studied, and then the range of reliability index of the equation of the maximum crack width is obtained.
