【摘要】 天津高银117大厦建筑高度597m,共117层,是中国在建的屋顶高度最高的建筑物,结构高宽比达到约9.5,均大大超过现行规范限值。为满足结构抗震与抗风的技术要求,结构采用含有巨型组合柱、巨型支撑及转换桁架组成的外框架以及含有组合钢板剪力墙的钢筋混凝土核心筒形成的巨型框架钢-混凝土混合结构体系。塔楼的结构高度、高宽比、巨型柱截面尺寸等均创造了中国现有建筑物的工程记录。结合新抗震规范的部分要求,作为在高震区设计建造的超高层建筑,在反应谱选取、整体刚度控制、材料与构件选型、性能化设计、巨型柱设计、防倒塌及稳健性分析、弹塑性动力时程分析等方面均体现了许多新的特点和设计要求。更多还原

【Abstract】 Tianjin Goldin 117 mega tower has an architectural height of 597m with total 117 storeies and the coronation of having the highest roof among all the buildings under construction in China.Structural height-width ratio is approximately 9.5,exceeding the existing regulation codes significantly.In order to satisfy the earthquake and wind-resisting requirements,a structure consisting of a perimeter frame(including mega composite column,mega brace and transfer trusses) and reinforced concrete core containing composite steel plate wall was adopted to form a mega frame steel concrete composite structural system.The tower keeps the records for structural height,height-width ratio and mega-column sectional dimensions among current Chinese engineering projects.Complemented by some of the new requirements in the latest Chinese building seismic design codes,design of the super high-rise building in high-intensity seismic area exhibits a number of new features and solutions to professional requirements in response spectrum selection,overall stiffness control,material and component type selection,seismic performance based design,mega-column design,anti-collapse and stability analysis as well as elastic-plastic time-history analysis.更多还原
