摘　　要：连体结构是现代建筑设计中常用的一种表现形式。以某高层不对称双塔连体结构为例,对连接体两侧塔楼的动力特性进行分析,表明本工程采用滑动连接的必要性。同时对本工程进行小震弹性分析、性能化设计和大震弹塑性分析,对连体部位进行专项分析,包括受力分析、挠度分析、关键节点有限元分析、滑动支座反力和位移计算等。结果表明,本工程结构方案设计合理,加强措施有效,抗震性能能够达到预期目标。连体部位受力良好、安全可靠,满足防碰撞和防坠落的设计要求。Connected structure is a common form of expression in modern architectural design.In this paper,the dynamic characteristics of towers on both sides of the connected structure are analyzed by taking a high-rise asymmetric twin tower as an example,which indicates the necessity of adopting the sliding connection in this project.At the same time,elastic analysis under minor earthquake,performance-based design,and elastic-plastic analysis under major earthquake are carried out for this project,with a focus on analysis of the connected structure,including force analysis,deflection analysis,finite element analysis of key points,and calculation of sliding support reaction and displacement.The results show that the structural design of this project is reasonable,the strengthening measures are effective,and the seismic performance can achieve the expected target.The connected structure has good mechanical properties,the structure is safe and reliable,and the design requirements for anti-collision and anti-falling are satisfied.
