【摘要】 本文以一座高墩大跨度连续刚构桥的设计实例为背景,建立起动力分析模型,对桥梁结构的动力特性进行了计算分析;并采用线性时程方法,输入实际地震波激励,对该结构在地震作用下的时程响应进行了分析研究,探明了高墩连续刚构桥在纵向、横向和竖向多维地震动作用下的响应特点,为该类结构的抗震设计提供参考。更多还原

【Abstract】 Taking a high-pier long-span continuous rigid frame bridge as construction background,dynamic model is built for this type of structure,the dynamic characteristic of this bridge is analyzed;Adopting linear time-history method,analysis on seismic behavior of high-pier long-span continuous rigid frame bridge is performed by using actual seismic wave excitation,the response of this type structure under multi-dimensional seismic wave excitation is studied;some useful conclusions are obtained and can provide references for seismic design of high-pier long-span continuous rigid frame bridge.更多还原
