摘　　要：近年来,装配式建筑技术体系不断取得改进与创新,模块化集成建筑成为了装配式建筑的重要发展方向之一。基于国内首个高度近100 m的混凝土模块化高层住宅项目,介绍其MiC技术应用创新,分析了混凝土集成模块对结构的刚度影响,并对结构进行抗震性能分析。结果表明结构设计时取周期折减系数为0.8来考虑模壳对结构刚度的影响是合适的;大震作用下剪力墙基本无损伤,大部分连梁达到重度损伤状况,满足结构性能目标;在核心筒四周及弱连接部位的楼板拉应力相对其它区域楼板拉应力较大,设计时楼板需要加强;弱连接楼盖在考虑构造加强的设计情况下可以满足结构承载力要求。In recent years,with the continuous improvement and innovation of assembled building technology system,modular integrated building has become an important direction of assembled buildings.Based on the first domestic nearly 100-meter-height modular integrated high-rise residential project,the innovation of the MiC technological application is introduced,also the impact of concrete modules on the structural stiffness and then the seismic performance of the structure are analyzed.The results show that it is appropriate to take 0.8 as the period reduction coefficient in the structural design to reflect the impact of modular shells on the structural stiffness.The shear wall is basi‐cally undamaged under the strong earthquake,and most of the coupling beams are severely damaged,meeting the structural performance goal.The tensile stress of the slabs around the core tube and the weak connection is larger than that of the slabs in other areas,so the slabs should be strengthened during design.The weak connection slabs can meet the requirements of structural bearing capacity in the case of considering strengthening details.
