Abstract:
In order to study the influences of different rise-span ratios on structural force of suspension bridge, taking Xihoumen bridge as prototype, authors established the finite element model by using bridge nonlinear calculation software BNLAS, which was developed by Southwest Jiaotong University. This model was a twin towers single-span suspension bridge and its main cable span was 485 m+1 650 m+485 m, it had single-span simply supported girder. The structural forces of suspension bridge with different rise-span ratios(1/8,1/9,1/10,1/11,1/12,1/13,1/14 and 1/15)were compared. The analysis results show that different rise-span ratios change the stiffness of structure, and lead different load effects.
