Analysis of Static and Dynamic Characteristics of Continuous Rigid Frame Bridge with High Pier and Long Span

Abstract

The design of health monitoring scheme for long-span continuous rigid frame bridge with high piers includes the determination of monitoring indexes, the types of sensors and the installation positions, etc. In this paper, the Baijianhe Bridge is taken as the engineering background, and the MIDAS software is used to carry out the finite element modeling analysis, the static characteristics and dynamic response of the bridge under live load, dead load and temperature load are analyzed. It is found that the maximum values of stress and deflection occur at the mid-span position and the joint surface of pier and beam, which should be monitored in real time.
