| 摘 要： | 按极限平衡法计算四边支承钢筋混凝土矩形板在均布荷载作用下的破坏简图,推导了钢筋混凝土矩形板在线性分布荷载作用下的极限强度近似计算公式。它和均布荷载的计算公式相同,仅将荷载集度以线性分布荷数的平均集度代替。与“精确”公式的计算结果相比较,误差在工程计算所允许的范围以内。

| Abstract: | In this paper, an approximate limit analysis of rectangular reinforced concrete slabs under linearly varying distributed loads based on the limit design yield-line pattern at failure for the case of uniformly distributed loads is examined. The formula derived is found to be the same as that of the uniformly distributed loads provided the load intensity is replaced by the average intensity of the linearly varying distributed load. The computed results are compared with those obtained by the rigorous method. It is proved that the possible errors will be within the permitted limit in engineering practice. |
