摘要随着社会经济的发展和建筑技术的革新，房屋的建筑高度不断攀升，国内外越来越多的专家学者投入到结构的抗风设计中，然而相比连体结构在地震激励下的响应分析，关于其风振响应的研究还不成熟。本文以高层连体建筑结构为研究对象，对其进行合理简化，抽象出计算模型，建立动力学方程；采用复模态分析法，选择共轭复指数随机风速谱模型，推导出结构在平稳随机激励下的响应表达式；最后运用MATLAB软件编制程序求解。65354

本文分别探讨了连接装置的设置位置，及其刚度、阻尼等力学参数对高层连体建筑结构在强风作用下的振动响应的影响，为进一步利用连接装置控制结构的风振响应奠定了基础。

Title Strong Wind-Induced Vibration Response Analysis Of High-Rise Double-Tower-Connected Structure                     

Abstract

With socio-economic development and construction technology innovation, the height of buildings has been increasing, as well as the influence of wind loads on them, which results in more and more experts and scholars at home and abroad dedicating to the wind-resistant design of building structure. However, compared with seismic response，analysis on wind-induced vibration of multi-tower-connected structure is not mature. The paper focuses on high-rise connected structures, building analysis model and establishing dynamic equations. Based on the complex mode analysis theory, the computational expressions of the mean square value of structural displacement, velocity and acceleration responses under stationary random excitation are developed. 

This paper discusses the influence of the setting position of connected devices and other mechanical parameters on the vibration responses of the double-tower-connected high-rise buildings in strong winds, which will lay a foundation of further study on controlling the wind-induced structural vibration responses of high-rise buildings.

Keywords  high-rise connected structure  wind-induced response
