Seismic Response Analysis of the Semi-Floating System of Long Span Cable-Stayed Bridge
According to the seismic performance of cable-stayed bridge with a project example, using finite element analysis method, establishing the space beam element and link element calculation model, the dynamic characteristic and the seismic response of the cable-stayed bridge with selected three earthquake waves were calculated, the results were compared with the of the response spectrum method.The results show that:the semi-floating system of cable-stayed bridge is great flexibility, the vibration cycle is generally longer; the results by using the response spectrum method are smaller; the cable-stayed bridge should be calculated in accordance with the specific circumstances of the project with multiple seismic waves.
