Abstract

Three cross-shaped columns were tested under low cyclic loading in order to research the effect of stirrup ratio on seismic behavior of cross-shaped columns with HRB500 reinforcement. The damage characteristic, hysteretic curve, load, displacement, ductility and accumulated damage were analyzed. The result show the damage characteristic is improved, the hysteretic performance has great improvement and the ductility of cross-shaped columns is enhanced with the increase of volume stirrup ratio. Besides, the degree of accumulated damage of specially shaped columns with HRB500 reinforcement can also be lighten.
