[提要] 闡述了作者在鋼筋混凝土矩形板受沖、剪作用方面的試驗研究成果。結(jié)合試驗成果，對現(xiàn)行混凝土結(jié)構(gòu)設計規(guī)范中鋼筋混凝土板的受剪承載力計算方法進行了討論。給出了適用于任意寬跨比的鋼筋混凝土矩形板的受沖、剪承載力計算方法，并提出了鋼筋混凝土矩形板受剪的設計建議，可供新一輪的混凝土結(jié)構(gòu)設計規(guī)范修訂時參考。

The proposed calculation methods for bearing capacity of R.C. rectangular slabs under punching or shearing are presented which can be used for rectangular slabs in any width-span ratio. And the design proposals are given. These design proposals will give a reference to the concrete structures design codes which is being revised.
Keywords: R.C.rectangular slabs; punching; shearing; width-span ratio; bearing capacity
