Seismic Analysis of Urban Elevated Continuous Bridges Installed Different Damping Devices

Abstract:

Earthquakes are human recognized natural disasters, causing tremendous loss of life and property to human society, so how to strengthen the seismic capacity of the building more effectively is one of the challenges faced by scientists.While the use of a damping device is an effective method. With the rapid economic and social development, the urban transport problem is an extremely serious livelihood problem faced by all countries. To solve urban traffic congestion, in many cities setting up viaducts is a widely used way to ease urban traffic pressure, and elevated expressways are the main bridges among continuous bridges. In order to ensure the safe operation of the urban elevated road system, we must make the correct evaluation of their seismic capacity. This paper focuses on the continuous beam bridge seismic response history analysis of installing viscous dampers and lock-up devices,compared with the general scheme of continuous bridge.
