单跨混凝土曲线梁桥地震反应简化计算方法
Simplified Calculation Method of Seismic Response for Single-span Concrete Curved Girder Bridges
摘要
Abstract
The curved girder bridges are used widely in city viaducts, interchanges and high-grade highway in China and abroad for its structural advantages and architectural aesthetics. However, severe damage even collapses of curved girder bridges were often occurred during the past damage earthquakes. This implies that the problem of seismic design of curved girder bridges has not been solved perfectly. In this paper, the finite element model of a typical single-span concrete curved girder bridge is built for numerical analysis. The parameter analysis method is employed in the numerical analysis to study the effects of main design parameters, such as curvature radius, span-width ratio, span-depth ratio and span, on the seismic response of single-span curved girder bridges. The center angle limits of a single-span curved girder bridge which can be seen as a regular bridge are given. A simplified method for calculation the seismic response of a irregular single-span curved girder bridge is also proposed.关键词
