Abstract:
Plastic theory is used in this paper to calculate the ultimate shear strength of rectangular RC beams simply supported.With the assumption that reinforced concrete was perfectly rigid-plastic,a kinematically admissible failure mechanism suitable for the shear failure of rectangular beams was presented and based on which theoretical calculation formulas were derived. The results of calculation are conformable to the test data of 120 beams tested in home and abroad.The test of 18 beams done by the authors proved that the failure mechanism proposed is realistic.Lastly,the theoretical formulas were simplified to be easily used in engineering design and be refered in modification of the Code.
