摘　　要：龙光总部中心为两栋“钢管混凝土叠合柱框架-核心筒”结构塔楼及钢桁架在高位形成的多重复杂连体结构。详细介绍了该结构的基础设计、结构体系的选型,从结构整体性能指标、结构抗震性能目标、结构最大层间位移角、剪重比等方面全面阐述了结构的设计策略,并对结构进行连体多塔与单塔包络设计。结果表明,结构各项指标均满足规范要求,结构具有足够的安全冗余度。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 of the structure and the selection of the structural system were introduced in detail.The design strategy of the structure was described 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 of multiple connected towers and single tower was carried out.The results show that all indicators of the structure meet the requirements of the specification,and the structure has sufficient safety redundancy.
