In each group , under the same reinforcement ratio , one specimen used uniform reinforcement and the other set concealed column . The models were tested under quasistatic , reversed cyclic horizontal loads in order to investigate the seismic performance under different reinforcement layout pattern . Based on the experimental results , seismic performance of the rectangular section SPW such as failure pattern , failure mechanism , characteristic loads , ductility and energy dissipation etc . were investigated. The results show that the seismic performance of the rectangular section SPW with concealed column is better . It is proposed that the concealed column should be planted at the rectangular section SPW.
