Abstract:
The effects of the shear-span ratio, concrete strength, longitudinal reinforcement ratio, member height and other factors on shear strength of reinforced concrete members without or with stirrups based on GB 50010—2002, ACI 318-08, EN 1992-1-1:2004, as well as CSA A23.3-04 were comparatively analyzed. Based on a lot of experimental results about shear capacity of reinforced concrete beams, shear capacity calculation formulas were studied, then reliability analysis performed by method of first-order second moment was presented. The maximum or minimum stirrup ratio and stirrup spacing requirements were comparatively analyzed. The results show that average reliability indexes of shear strength for reinforced concrete members without or with stirrups designed according to Chinese code are greater than those of Canadian code, but smaller than ACI code and European code. For the minimum ratios of stirrups, European code is a little greater than Chinese code, and is greater than ACI code and Canadian code. For the maximum spacing of stirrups, the four codes are mostly the same when the member section height is small, with member section height increasing, European code is greater than ACI code and Canadian code, and Chinese code is the smallest.
