摘要
根据部分钢筋在支座附近切断或弯起的 Ｒ Ｃ 双向板可能形成的各种破坏机构，得出了其相应的极限承载能力公式，同时对公式中的主要参数取值做了详细讨论，如长短边之比、两方向跨中设计弯矩之比和支座设计弯矩与跨中设计弯矩之比，并给出其在设计中的取值原则。
On the basis of various possible failure mechanisms of two way RC slabs supported on four sides with cut off or bent up reinforcements near the supports, their corresponding ultimate bearing capacity formulas are introduced. The main parameters in the formulas are studied in detail, such as the ratios of length to width, design bending moments at middle spans in the two directions and design bending moment at support to that at middle span, and the criteria for the selection of such parameters in design are also provided.
