基于103 m+190 m+103 m连续刚构桥的桥墩抗震分析研究

Study on Anti-earthquake of Piers Based on Continuous Rigid Frame Bridge with 103 m+190 m+103 m

目前,桥梁结构的抗震分析已被人们所广泛关注,因为地震的发生不仅会在一定程度上对人们的正常出行造成影响,还会直接影响我国经济的正常运行。鉴于此,以某连续刚构桥为研究对象进行抗震分析,分别验算其在E1和E2地震作用下的响应结果,验算的主要内容包括E1地震作用下桥墩的强度是否满足规范要求和E2地震作用下桥墩的抗剪和墩顶位移是否均满足规范要求。

The study of anti-earthquake on bridge structure has been widely concerned recently is that the occurrence of earthquake will not only affect people's normal travel to a certain extent,but also impede the economic development directly.In view of this,a continuous rigid frame bridge was taken as the research object for anti-earthquake analysis here to check the response results of the bridge in earthquake effect E1 and E2 respectively.The main contents of the test include:whether the strength of piers under the effect of E1 and the shear resistance of the bridge pier and the displacement of the pier top under the effect of E2 are meet the requirements of the specification.
