［摘要］武漢保利關山村K26地塊項目為四塔多重復雜連體結構，項目包括兩棟172.6m的高塔和兩棟45.0m的矮塔。四塔分別在2層、10~11層、22~23層設置3道連體，造成結構嚴重不規(guī)則；著重介紹了該項目抗震性能化設計情況，并對連體結構、塔樓連體位移特性、混凝土收縮徐變對高低塔連體的影響、整體結構破壞機制、核心筒偏置進行了分析。分析結果表明，主體結構抗震性能滿足規(guī)范要求，結構能夠滿足安全要求。
［關鍵詞］復雜連體結構； 鋼桁架； 收縮； 徐變； 核心筒偏置； 抗震性能化設計

Abstract:Wuhan Guanshancun K26 Plot project developed by China Poly Group Corporation is a four-tower multiple complex connected structure; The project consists of two 172.6m high towers and two 45.0m low towers. The four towers are respectively set three connections on the 2nd floor, 10~11th floors and 22~23th floors, which cause serious irregularities of the structure. The seismic performance-based design of the project was specifically introduced, and thus the connected structure, the displacement characteristics of the tower connection, the influence of concrete shrinkage and creep on the high and low tower connected corridors, the failure mechanism of the overall structure, and the core wall offset were analyzed. The analysis results show that the seismic performance of the main structure meets the requirements of the code, and the structure can meet the safety requirements.
Keywords:complex connected building; steel truss; shrinkage; creep; core wall offset； performance-based seismic design
