Shaking Table Test of Multi-Tower Self-Anchored Suspension Bridge

Abstract:

As a new kind of bridge structure, multi-tower self-anchored suspension bridge (MSSB) has complicated mechanical characteristics. So far, the research on dynamic performance of MSSB is limited to theoretical and numerical simulation. Based on the first three shaking table system in China, shaking table test of MSSB is carried out. The modal test and seismic excitation test show that the performance of fundamental mode shape is anti-symmetric vertical bending vibration of girder, coupling with longitudinal bending vibration of middle tower. Seismic response of middle tower is greater than side towers. At last, 3D finite element model of test specimen is established and test process is numerical simulated by FEM. Simulated result is agreed well with test record.
