Study on Collapse-mechanism of Long Span and High-pier Continuous Rigid Frame Bridges during Strong Earthquake

摘要：

In this paper, dynamic response of long span and high-pier continuous rigid frame bridges (70m+127m+70m) during strong earthquake is studied with damage model of reinforced concrete by the explicit dynamic analysis code. The development of the concrete elements from cracking to failure and the bridge from part collapse to the whole collapse of the bridge are studied. The damage and collapse mechanisms during strong earthquake are given of Long Span and High-pier Continuous Rigid Frame Bridges. References are provided for seismic analysis of this kind of bridges.
