摘要
取某特大桥的一联三跨,采用纤维单元建立两种型式钢管混凝土桥墩的桥梁有限元模型,输入MAXICO地震波,采用非线性时程分析法,计算两种型式钢管混凝土桥墩顺桥向地震响应,并比较在常遇地震和罕遇地震作用下两种地震响应的差异,根据响应结果对两种钢管混凝土桥墩的优劣进行初步讨论。
This paper establishes the bridge finite element model of two types of concrete -filled steel tubular pier by fiber unit, inputs Mexico seismic wave, and calculates their seismic performance by using nonlinear time -history method. According to the results, compares the differences of seismic response under condition of often met earthquake and rarely met earthquake, and discusses the advantages and disadvantages between two types of bridge pier.
