夹层橡胶垫基础隔震框架结构非线性时程分析

摘要
采用大型有限元分析软件ANSYS,对基础隔震与传统抗震的多层钢筋混凝土框架结构进行了地震反应时程分析。对比基础隔震与传统抗震结构在同一地震波输入下的动力反应,研究2种结构模型的加速度、层间剪力、层间位移以及阻尼比对减震效果的影响。研究结果表明:钢筋混凝土框架结构采用基础隔震技术之后,结构地震反应明显降低。
The large finite element software ANSYS was used to analyze dynamic time history of the base-isolated and the base-fixed multistory reinforced concrete frame structure.The earthquake response of building under the same seismic condition was compared with accelerations,floor shear,floor displacement and damping ratio between the base-isolated and the base-fixed structure.The results show that the seismic response of reinforced concrete frame structure obviously reduces with base isolation technology.
