装配式钢筋混凝土管型通道地震响应分析
Seismic response analysis of prefabricated reinforced concrete tubular channel
【摘要】 文章通过沿人工边界设置一系列由弹簧和阻尼器组成的简单物理元件的黏弹性人工边界来模拟无限地基,建立了土-装配式钢筋混凝土管型通道地震动力相互作用的二维有限元模型。利用ANSYS中APDL参数化语言编制了相应的程序,对某装配式钢筋混凝土管型通道进行了地震响应分析,探讨了其动力反应特性及动力响应规律,以期对实际工程建设有所裨益。
【Abstract】 A viscoelastic artificial boundary composed of a set of viscous-spring and damper that is set along the artificial boundary is used to simulate the infinite soil foundation.A two-dimensional finite element contact model for the seismic analysis of soil and prefabricated reinforced concrete tubular channel is presented.By using the parametric design language APDL in ANSYS program,the corresponding analysis program is designed.The seismic response of a prefabricated reinforced concrete tubular channel is analyzed,and the discipline and feature of its dynamic response are discussed.The conclusions can be useful to the engineering construction.
【Key words】 prefabricated tubular channel； two-dimensional contact model； interaction of soil and structure； viscoelastic artificial boundary； seismic response；
