| 摘 要： | 本文用塑性极限方法对钢筋砼板的冲切承载力进行了研究。所采用的冲切破坏机构同时考虑了冲切锥与外围板之间的相对错动位移和转动位移的影响,比较符合实际的冲切破坏机理。得到的冲切承载力计算公式,形式简单,与试验结果较为符合,能反映出弯曲钢筋所作的贡献。

| Abstract: | In this paper, the plastic limit method is used to investigate the strength of reinforced concrete slabs in punching shear. The assumed collapse mechanism takes accounts of the influence of shear displacement and rotation simultaneously and conforms to the real features of punching failure satisfactorily. The formula obtained can reveal the contribution of flexural reinforcement to punching shear strength. |
