| Abstract: | Previous researches on shear behavior of inclined sections in reinforced concrete beams used to be carried out on a comparatively high longitudinal reinforcement ratio in the codes of various countries.However,the shear design methods based on the data obtained from these researches may have distinguished deviations.This paper studies the shear behavior on a comparatively low longitudinal reinforcement ratio.Research has indicated that different longitudinal reinforcement ratios have significant impact on the shear behavior and the development of cracks in the beams,and the shear design equation in the code applied to beams without wed reinforcement restrained maybe not safe enough. |
