昆山金鹰高层酒店结构总高度为220.8m,建筑地面以上49层,地面以下2层,结构采用框架-核心筒混合结构体系。在标高129.1m避难层处设置三道伸臂桁架及环带桁架,在标高192.1m避难层处设置二道伸臂桁架。结构存在部分薄弱层,在强烈地震作用下,结构薄弱部位会产生较大的塑性变形,采用动力弹塑性分析手段找出结构薄弱部位,对此部位采取加强或性能设计措施,确保关键构件不破坏,层间弹塑性位移角能满足规范要求。针对超限情况和结构特点,对不同的抗侧力构件提出合理的抗震性能设计目标,满足结构体系安全可行。
The total height of the Kunshan Golden Eagle High-rise Hotel is 220.8m, 49 floors above the building floor and 2 floors below the ground. The structure adopts the frame-core tube hybrid structural system. At the level of 129.1m refuge shelter set three stretcher truss and belt trusses, at the level of 192.1m refuge layer set two stretcher truss. There are some weak layers in the structure. Under the strong earthquake, large plastic deformation will occur in the weak parts of the structure. Dynamic elastic-plastic analysis method will be used to find out the weak parts of the structure. This area is designed with strengthening or performance design to ensure that the key components are not damaged , Layer elastic displacement angle to meet the regulatory requirements. Aiming at the characteristics of overrun condition and structure, aiming at the different anti-sideforce components, the reasonable design goals of anti-seismic performance are put forward to meet the requirement of structural system safety and feasibility.
