摘　　要：对于简单边界条件的钢筋混凝土矩形板的极限分析已有成熟的方法.对于复杂边界条件的钢筋混凝土矩形板的极限分析也有一些方法,但这些方法在使用中会受到很多限制.本文基于实验研究的结果,利用将直板带与斜板带相结合的方法,找到一种适用于各种情况的实用的方法对复杂边界条件钢筋混凝土矩形板进行极限分析.文中根据试验结果,推算出斜板带的计算跨度和长度系数,利用本文给出的方法及长度系数,对复杂边界条件钢筋混凝土矩形板进行极限分析,可以得到满意的结果.Limit analysis of rectangular reinforced concrete slab with simple boundary conditions is already mature for rectangular reinforced concrete slab with complex boundary conditions limit analysis Although there are some ways, many restrictions will be in use. Based on the results of experiment research, a practical method which includes orthogonal and inclined strips is found for limit analysis of reinforced concrete rectangle slabs with complex boundary condition. According to the method and span length coefficient in this paper, the satisfactory result can be got at limit analysis for rectangular reinforced concrete slab with complex boundary condition.
