摘要: 云南康美健康體驗中心位于昆明市呈貢區(qū),建筑±0?? 000 標高以上為圓形多塔結構鋼管混凝土柱鋼框架結構,采用可自然采光通風的半開敞地下室作為隔震層,對上部多塔結構整體隔震,隔震層層高 5?? 4m,隔震支座布置于地下室柱上端外墻開敞標高范圍,形成長下支墩。 對比了多塔結構抗震和隔震的動力行為,對隔震相關設計參數(shù)和長下支墩對減震效果的影響進行了分析,并提供了關鍵部位設計構造做法。

關鍵詞: 多塔結構; 大底盤; 基礎隔震; 鋼結構; 長下支墩

Abstract: Yunnan Kangmei Health Experience Center is located in Chenggong District of Kunming. Above the zero point of relative elevation of the building, it is a circular multi?tower structure with a steel tube concrete column steel frame structure. The semi?open basement with natural lighting and ventilation is used as the seismic isolation layer to isolate the seismicity from the upper multi?tower structure. The height of the seismic isolation layer is 5?? 4m. The isolation bearing is arranged in the open elevation range of the exterior wall at the upper end of the basement column to form a long lower buttress. The dynamic behaviors of seismic and isolation of multi?tower structure were compared, the related design parameters of seismic isolation and the influence of long lower buttress on the damping effect were analyzed, and the design and construction methods for key parts were provided.

Keywords:multi?tower structure; large chassis; foundation seismic isolation; steel structure; long lower buttress
