摘　　要：国家会议中心二期配套酒店项目为大底盘多塔结构,北侧X形塔楼与南侧L形塔楼通过2层裙房连接。地上部分采用钢管混凝土框架-支撑结构体系,存在扭转不规则、偏心布置、凹凸不规则、楼板不连续、竖向抗侧力构件不连续、多塔、斜柱、穿层柱等多项超限不规则项。介绍了结构体系选型、超限设计要点、屈曲约束支撑减震分析,采用抗震性能化设计、动力弹塑性分析等验证了设计的可靠性。创新性设计了一种钢管混凝土柱转换节点,给出了该节点的构造,并通过拟静力试验验证了节点的可行性,可为同类工程提供参考。The supporting hotel project of National Convention Center PhaseⅡis multi-tower structure with large chassis,the X-shaped tower on the north side and the L-shaped tower on the south side are connected by a 2-story podium.The above-ground part adopts concrete filled steel tube frame-support structure system and there are many irregular items such as torsion irregularity irregular,eccentric layout,convex irregularity,floor discontinuity,vertical lateral force resistance component discontinuity,multi-tower,inclined column,and through-layer column.The selection of structural system,the key points of out-of-code design,and the vibration absorption analysis of buckling constrained support were introduced.The reliability of the design was verified by the seismic performance design and dynamic elastic-plastic analysis.A kind of concrete-filled steel tube column conversion node was innovatively designed,the structure of the node was given,and the feasibility of the node was verified by quasi-static test,which can provide reference for similar projects.
