According to the author's experimental results of R.C. rectangular slabs under punching or shearing, the calculation methods of shear bearing capacity of R.C. slabs which are used in design codes of concrete structures are discussed. 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
