Abstract

It is reported that RC members fail in shear after flexural yielding even if the shear strength is greater than the flexural strength. However, the shear failure mechanism of RC members is complicated and not well understood. We tested RC members where the test parameters were axial forces and loading histories. The following conclusions were obtained: (1)The latest AIJ guidelines slightly underestimate the influence of the hoop interval on ductility and overestimate that of cross-ties. (2)Axial forces delay the strength deterioration. However, the damage after the strength deterioration accumulates faster than the case of no axial forces. (3)Strength deterioration starts when tangential relative displacement along a crack becomes larger than a threshold, which is not affected by loading history.
