【摘要】 高层建筑设置转换层已成为现代高层建筑发展的一大趋势,然而,带转换层复杂高层建筑由于竖向构件不连续导致其抗震性能较差,单纯依靠传统的体系和方法设计这类建筑,结构安全难以保证。文章提出一种新型分段隔震体系,以该体系的技术来源和基本原理为基础,从随机振动理论和能量平衡原理出发,提出了基于能量的被动控制参数分析方法。通过MATLAB编程对算例工况进行参数分析,得到了控制参数对隔震层位移方差及隔震层滞回耗能占地震总输入能量比值的影响规律,以期为带转换层复杂高层建筑的耐震设计开辟一条新的途径。更多还原

【Abstract】 High-rise building with transfer story has become the developing trend of modern high-rise buildings,while the earthquake resistance of the complex high-rise building with transfer story is so poor due to the dis-continuity vertical components.It is difficult to ensure the safety of these buildings using traditional systems and methods.A new segmented isolation system is proposed.In this papert,he technology sources and the basic principles of segmented isolation are summarized,and the random vibration theory and the principles of energy balance are adopted to establish the method of energy-based parameters analysis.Meanwhilet,he influencing law of the isolation layer displacement variance and the energy ratio are obtained by analyzed the case structure parameters through MATLAB software programming,which is expected to provide a new promising approach for the seismic design of complex high-rise buildings with transfer story.更多还原
