Analysis of statical and dynamical test of large span one tower cable-stayed bridge

Shi Zhou, Cao Fahui, Pu Qianhui  
Test the deflection of the beam and the tower, the change of tension of the cables, and the stress of the beam and the tower of Yibin Zhongba Jinshajiang River Bridge(one tower 252 m-span cable-stayed bridge) under static loads. The test results indicate that the structure has enough stiffness and strength .The natural vibration of the structure is tested, and the impact of the passing vehicles is analyzed. And the uses of results of static and dynamical tests in damage detection during the service period of the bridge is analyzed.
