Dynamic Analysis of Partial Cable-stayed Bridges

Li Shiguang, Yan ZhihuaAurhor’s address The 3 rd Railway Survey And Design Ins titute, Tianjin 300142  
A partial cable\|stayed bridge’s dynamic behaviors were analyzed. According to the characteristic of girder fixing with the towers and separating from the piers, a study was conducted on the impact of joint act ion of superstructure and substructure and the change of elastic modulus of conc rete on partial cable\|stayed bridge’s dynamic behaviors. The results are compa red with those obtained by experiment, the conclusion are made from comparison. When partial cable\|stayed bridge’s dynamic behaviors were analyzed, joint ac tion of superstructure and substructure should be taken into account and the cha nge of elastic modulus of concrete can be neglected.
