Beam Bridge

Continuous beam bridge was widely used, while seismic problem of it was prominent in meizoseismal area. According to seismic-isolation principle and mechanism of PSD, seismic performance of PSD were studied and the parameters of PSD were analyzed later, based on south approach of North Branch of Xia-Zhang Sea-Crossing Bridge. It was found that PSD, a combination of preloaded spring and liquid viscous damper, was an effective seismic-isolation device which could significantly reduce the seismic response of continuous beam bridge in longitudinal and transverse direction. Damper coefficient was the main parameter of PSD, while preloaded force, linear spring stiffness and damper index had a little effect on seismic performance of PSD.

The City

Construction of Fozhao intercity bridge in Guangzhou was a three-span prestressed concrete continuous beam bridge. The bridge adopted triangle hanging basket cantilever pouring construction method. The bridge mixed cable-stayed spans, H form tower and typical highway bridge elements. It spaned across the exiting transport hubs center, with modern and ethereal shape, and became a new landmark of the city.
