Dynamic Performance Analysis of Continuous Rigid-Frame Bridge with Different High-Pier

摘要：

Using the finite element program software-ANSYS, this paper analysis of Xing Gou Bridges dynamic performance in different ways such as using fourcolumn reinforced concrete bridge pier, two thinwalled solid pier, the single-column solid pier. Studies have shown that in the condition of the same pier cross-sectional area, the vibration frequency of these three piers presented in turn increase. And when use of four-column-type pier and two thin-walled solid pier, the data is closer to each other, and there is a big difference when use of the singlecolumn solid pier. Vibration of the former two types of bridge is mainly about high bending, while the single column pier is in the main of the bridge system. Under the action of seismic waves, because the predominant period of seismic waves and the structure of the vibration is in different characteristics, etc., the structural dynamic response is different.
