摘要: 龍光總部中心為兩棟“鋼管混凝土疊合柱框架-核心筒”結(jié)構(gòu)塔樓及鋼桁架在高位形成的多重復雜連體結(jié)構(gòu). 詳細介紹了該結(jié)構(gòu)的基礎設計、結(jié)構(gòu)體系的選型,從結(jié)構(gòu)整體性能指標、結(jié)構(gòu)抗震性能目標、結(jié)構(gòu)最大層間位移角、剪重比等方面全面闡述了結(jié)構(gòu)的設計策略,并對結(jié)構(gòu)進行連體多塔與單塔包絡設計. 結(jié)果表明,結(jié)構(gòu)各項指標均滿足規(guī)范要求,結(jié)構(gòu)具有足夠的安全冗余度.
關鍵詞: 框架-核心筒結(jié)構(gòu); 連體結(jié)構(gòu); 鋼管混凝土疊合柱; 模態(tài)分析; 抗震性能目標; 包絡設計

Abstract: Logan Headquarters Center is composed of two " concrete-filled steel tube composite column frame-core tube"structural towers and steel trusses, which form multiple complex connected structure at high positions. The basic design ofthe structure and the selection of the structural system were introduced in detail. The design strategy of the structure wasdescribed comprehensively from the overall performance index of the structure, structural seismic performance target,maximum inter story displacement angle of the structure, shear weight ratio, etc. , and envelope design for the structure ofmultiple connected towers and single tower was carried out. The results show that all indicators of the structure meet therequirements of the specification, and the structure has sufficient safety redundancy.
Keywords:frame-core tube structure; conjoined structure; concrete-filled steel tube composite column; modal analysis;seismic performance objective; envelope design
