大连嘉和广场A座塔楼高度为184.5m。介绍了基础设计、结构体系和特点,分析研究了钢管混凝土柱钢框架-混凝土核心筒结构的性能化设计,满足C级抗震性能目标,在25,38层设置两个伸臂桁架结构加强层,增强抗侧移刚度,减小层间位移;在底部加强区及加强层之间设型钢暗柱,提高延性。通过静力弹塑性分析、验算结构在罕遇地震下的抗震性能。 Block A, Dalian Jiahe Plaza, a tower height of 184.5m. The basic design, structural system and characteristics are introduced. The performance design of steel tube-concrete core column structure of CFST column is analyzed and designed to meet the C-level seismic performance goal. Two strengthening structures of boom structure are set up on the 25th and 38th floors, Enhance the anti-lateral stiffness, reduce the interlayer displacement; in the bottom of the reinforced area and reinforced layer between the design of dark columns to improve ductility. Through the static elasto-plastic analysis, the seismic performance of the structure under rare earthquakes can be checked.
