摘要
该文以京承高速公路潮白河大桥为工程背景,介绍了三塔部分斜拉桥结构体系的选择过程,并通过数值分析比较了不同结构体系在外部作用下的反应,以及采用阻尼器降低结构地震效应的措施。
Taking Chaobai River Bridge in Jingcheng Expressway as the engineering background, the article introduces the selection process of 3-phlon partial cable-stayed bridge structural system, and through the numerical analysis, compares the reactions of the different structural systems under the external action, and uses the measures using damper to reduce the earthquake effect of the structure.
