【摘要】 隔震技术因其杰出的减震效果、经济性、适用性和耐久性而被广泛应用。本文运用ETABS软件,建立了四种带地下室隔震结构的模型,通过对比自振特性、受力及变形特性、减震效果等,来研究结构模型建立方法的不同对计算结果的影响。结果表明:对于非隔震结构,地下室周边土体约束作用越弱,上部结构地震响应越大;对于隔震结构,上部结构地震响应与地下室周边土体约束作用无关;约束作用减弱,减震系数减小。更多还原

【Abstract】 Seismic isolation technology is widely used for its considerable seismic resistance effect, economy, durability and applicability. In this paper, vibration characteristics, force and deformation characteristics and damping effects were contrasted to discuss the impacts of modeling methods on results based on ETABS.The results showed that, for non-isolated structure, seismic response of super-structure would increase as the earth pressure decreases. For isolated structure, seismic response of super-structure is unrelated to the earth pressures. And seismic decrease coefficient would decrease as the pressure decreases.更多还原
