Abstract:A large scale roundended pier model with low ratio of reinforcement is made, and the seismic performance of pier model is studied by pseudo dynamic test. The seismic responds and hysteretic curve of pier acted by real earthquake wave are gained.The seismic performance of pier model is analyzed and  the enduring actua l level of earthquake is given.
