Damping Value for Seismic Response Analysis of Long-Span Bridges

Abstract:

Article Preview

The current problems on damping in seismic response analysis of bridges is presented. The Rayleigh damping theory is simply introduced in this paper. Taking the Longtan River Bridge for instance, the finite element model of Longtan River Bridge (left line) is established. Then, the dynamic properties of the bridge is analyzed. Based on this, the Rayleigh damping constants and in an ANSYS dynamic analysis are obtained.
