Seismic Analysis on the Urban Bridge Using Visco-damper
摘要
Abstract
The basic seismic intensity of the east-north urban Bridge site is 8 degrees, and the basic design earthquake acceleration is 0. 20g. In order to address the seismic issues, the vibration energy dissipation technology of viscous fluid dampers is used. In this study, the finite element dynamic analysis of the seismic response is conducted depends on the commercial finite element software of ANSYS, the seismic bridge do earthquake response spectrum analysis and time history analysis. By comparing the results of the analysis, theoretically verified that the fluid viscous damper effectively reduces the seismic forces and improve the safety of the bridge. The bridge can be elastic state under strong earthquakes.关键词
