Experiment and Numerical Study on Shear Capacity of RC Beams
Based on cyclic loading experiment of six beams in the two groups, the relationship among the stirrup stress, initial diagonal crack width and shear capacity of RC beams was studied. Experimental result shows that the decline of the shear strength of the RC beams due to cyclic loading can be characterized by the width of diagonal crack, according to the experimental phenomena, a formula for shear capacity after cyclic loading is derived for engineering use. To study the mechanism of the capacity decline, considering the effect of the width of diagonal crack to the shear transfer coefficient, numerical analysis by FEM method was done, the result is compared to the experimental result.
