摘要
江苏海安中洋豪生超高层酒店地上40层,大屋面高度171.1m,为高度超限、扭转不规则的超高层结构。针对建筑功能、平面特点,在对不同结构方案进行比较和优化的基础上,结构体系选用框架-核心筒体系,楼盖体系采用现浇混凝土空心楼板。通过对底部加强部位核心筒剪力墙采用中震不屈服性能设计、控制框架柱轴压比和结构扭转效应、加强裙楼与塔楼连接部位设计、采用双连梁及型钢混凝土连梁等一系列抗震加强措施,保证结构具有良好的安全性能和使用性能。
The roof height of Zhongyang Haosheng super high-rise hotel building in Jiangsu Hai′an is 171.1m with 40 stories above ground,the structure of which with the characters of height exceeding limitation and plane irregularity.Based on the comparison of different structure plans,and with regarding to architectural function requirement and plane features,the structural system of frame-core-tube structure and cast-in-situ hollow concrete floor system were adopted.A series of measures,such as processing performance-based design to the bottom part of core-tube shear walls,controlling the axial compression ratio of columns and structural torsion effect,strengthening the design for the connecting part between tower building and podium building,adopting dual coupling beams and steel reinforced coupling beams,were taken to guarantee safety and fine service performance of the structure.
