摘　　要：无锡茂业城主塔楼地下2层,地上69层,大屋面结构高度291.6m,建筑高度304.1m。分别采用钢筋混凝土框架-核心筒结构体系和混合框架-核心筒结构体系,对两种结构体系进行技术经济对比分析。对比结果显示按市场价采用混合结构体系时结构工程造价增加351元/m2,仅占结构工程总造价的16.7%,但底层可增加有效使用面积21.0m2,占建筑面积的1.05%,且可以提高结构施工进度,减少5个月工期。综合而言,采用混合结构体系方案具有一定优势。The main tower of Maoye City in Wuxi has two levels of basement and 69 stories above ground. The structural height is 291. 6m and the building height is 304. 1 m. Two structural systems of RC frame-core wall and hybrid frame-core wall are compared technically and economically. Results show that hybrid frame-core wall structural system costs more of351 yuan / m2（ accounting for only 16. 7% of the total cost of the structure） and can increase effective use area of 21. 0m2on ground floor（ accounting for 1. 05% of the construction area）. Moreover,the hybrid frame-core wall structural system can save construction duration of five months. Overall,the hybrid frame-core wall structural system has comparative advantage.
