摘要
厦门英蓝国际金融中心T3塔楼为双塔高位连体结构,地上37层,结构高度166m,在30～37层设置7层连接体,连接体跨度约40m。对整体和分塔模型进行了地震动力响应特性分析,由于连接体与塔楼相互影响,双塔连体时结构的扭转效应增加显著,连接体上下层侧向刚度突变明显,连接体相关楼板应力较大。通过罕遇地震弹塑性时程分析,对结构的薄弱部位采取相应的抗震加强措施。与反应谱分析方法相比,采用弹性时程分析方法研究高位连体结构的竖向地震作用效应更安全可靠。通过风洞试验研究复杂风环境作用下的高层建筑受力特性。
The T3 tower building of Xiamen Yinglan International Financial Center is a twin-tower high-position connected structure with 37 floors above the ground and 166 m in structural height. Seven-storey connector is installed on 30～37 floors with a span of about 40 m. The dynamic response characteristics of the whole and single-tower models were analyzed. Because of the interaction between the connector and the tower, the torsion effect of the twin-tower connected structure increased significantly; the lateral stiffness of the upper and lower layers of the connector had obvious mutation; and the relevant slab stress of the connector was large. Through the elasto-plastic time-history analysis under rare earthquakes, the corresponding seismic strengthening measures were taken for the weak parts of the structure. Compared with the response spectrum analysis method, it was safer and more reliable to use the elastic time-history analysis method to study the vertical seismic effect of high-position connected structures. Through wind tunnel test, the mechanical characteristics of high-position connected buildings under complex wind environment were studied.
