摘要

为提高高烈度抗震设防区建筑的安全性及抗震性能,国家和地方颁布了一系列政策,鼓励并推广使用减隔震技术。以云南省某规划展览馆为工程背景,提出了一种基础隔震与上部结构减震混合应用的减隔震组合技术,并将其应用于国内工程设计中。分析了该减隔震组合技术的减震效率及结构在罕遇地震作用下的抗震性能。分析结果表明:建议的减隔震组合技术具有良好的减震效果;在罕遇地震作用下,上部结构基本保持弹性,结构表现出良好的抗震性能。同时,针对该减隔震组合结构,提出了叠加分析法。通过算例分析,认为叠加分析法计算结果用于结构设计偏于安全。提出了适用于该减隔震组合结构的设计流程,以期为类似的工程设计提供参考。
        In order to improve the seismic performance and safety of buildings in high intensity area, national and local governments have promulgated a series of policies, encouraging the utilization of seismic isolation and energy dissipation technologies. This paper takes an exhibition hall located in Yunnan province as an example, proposes a kind of seismic isolation system combined with energy-dissipation technology, and adopts this system for engineering design in China. This paper analyzes both the seismic efficiency of the system and the structural seismic performance under rare earthquakes. The analysis results indicate that the system has great seismic efficiency and the superstructure of the system remains elastic under rare earthquakes, showing great seismic performance. Besides, this paper proposes a superposition analysis method for designing the system.According to the calculation results, the superposition method provides safe results for design. Finally, this paper proposes the design process of superposition analysis method for the system, which can be used as a reference for similar engineering cases.
