Cable Stayed Bridges

This paper focuses on the performance evaluation of long span cable-stayed bridge. Pushover method has been compared with RHA method to verify its validity. A specific bridge has been calculated by pushover analysis method using several different lateral load patterns. With four typical seismic analysis methods on the structure, the pushover analysis capacity curves have been compared with the RHA’s. It is demonstrated that the pushover method is accurate enough to be used in Engineering.

Cable Stayed Bridges

For long-span cable-stayed bridge, the stress of pylon anchorage zone is complex. For the construction technology personnel, the research on the force characteristics of anchorage zone can offer a theoretical base to organize construction better. This paper makes a further study for the stress of tower anchorage zone of two cable-stayed bridges with different anchor forms by using major general finite element program ANSYS to analysis the force characteristics of anchorage zone in detail. The results provide a reference for construct and design the same type structure. The analysis method for same type structure is also worth learning.

A single bent structure of PHC pile wharf was taken as the research object. A finite element model was established and studied by pushover analysis along the transverse direction by SAP2000. The parameter conversion relationship between response spectrum of ATC-40 and of Chinese codes was studied. Seismic performance evaluation of the wharf structure is conducted. The conclusion is that the single pile yield order of the PHC pile wharf is from the bottom to the top. The wharf structure meets the seismic capacity requirements on condition of frequent earthquake of 7 degree, but needs appropriate reinforcement on condition of rare earthquake of 7 degree.
