【Abstract】 The seismic behaviors of large-scale RC round-ended piers with low reinforcement ratio are studied with lab test. Ten pieces of specimens of RC piers are made for the pseudo-static test. It is stressed that the nonlinear hystersis, the ductility factor, the dissipated energy, and the extreme resistance are studied. The effects of both the shear span ratio and the reinforcement ratio have to be considered. It is found that the parameters of RC piers with low reinforcement ratio are obtained.更多还原
