| 摘 要： | 针对带转换层复杂高层建筑抗震性能较差的缺点,提出新型的分段隔震体系.本文从随机振动理论和能量平衡原理出发,建立了基于能量的分段隔震结构被动控制参数优化方法.通过MATLAB编程对算例进行多工况参数分析,获得了控制参数对隔震层与地震总输人能量的比值的影响规律:中间隔震层位于结构中部附近时,存在最优频率比和阻尼比使得隔震层...

| Abstract: | This paper proposes so called segmented isolation system to improve the poor seismic performance of complex high-rise building with transfer story.The random vibration theory and the principle of energy balance are adopted to develop the method of energy-based parameters optimization.Subsequently,the variation of the ratio of the isolation layer hysteretic energy to the total seismic input energy is shown by analyzing the structure parameters.When the location of the intermediate isolation layer is approxim... |
