Abstract In order to further study the seismic behavior of reinforced concrete hollow bridge columns and factors influencing，five reinforced concrete hollow bridge columns models with large ratio were built and tested to failure under the combined action of constant axial load and reversed cyclic laterl load.The aim of this paper is to evaluate seismic performance of all the five models，and variables included longitudinal reinforcement ratio，spiral reinforcement ratio，axial load ratio，influence seismic performance，such as failure mode，hysteretic behavior，load-carrying capacity，ductility. Analysis of the experimental results suggest that the seismic performance of reinforced concrete hollow bridge columns is great，influence of variables obey the theory of reinforcement concrete.With such hollow pier in engineering，we can save material dramtically，and have enough security of safety.
