| Abstract: |
In this paper, we take the suspension bridge of Oujiang Beikou bridge in Wenzhou, as the engineering background, the effects of a full rigid connection between segments, adding restraint cables between the stiffening beam and bridge tower, and adding restraint cables between the main cable and bridge tower, addition underwater auxiliary pier and the combination of the above measures on the natural vibration characteristics of the structure are studied and compared, especially the influence of torsional frequency and vibration mode. The calculation results show that when the hoisting quantity of stiffening beams is small, setting cables or a combination of the rigid connection of the beam and setting cables can improve the torsional frequency of the structure. When the hoisting quantity of stiffening beams is large, setting cables or combination setting auxiliary pier and rigid connection of beam |
