Application of Lead Rubber Bearing in Curved Continuous Bridge

Abstract:

Based on the general FEA program, the bidirectional nonlinear behavior of lead rubber bearing is taken into account by using two orthogonal nonlinear spring elements. Considering the effect of radius of curvature, lead diameter and dissimilar seismic motions, dimensional FEA model of seismically isolated curved continuous bridge is established. And the seismic energy response analyses for seismically isolated curved continuous bridge are carried out under the three-dimensional seismic motions. So, some meaningful references are provided for the design of vibration absorption and isolation of the curved beam bridge in this paper.
