摘要
随着科学技术的发展,高层建筑的高度不断增加,轻质高强材料被广泛使用,同时出现了大量复杂体型的双塔或多塔建筑结构形式,这对高层建筑抗风设计带来了新的问题。目前针对单体高层建筑的风振研究较多,而对于复杂体型多塔楼高层建筑风振研究较少,本文结合萧山国际商务大楼工程,对具有复杂体型的双塔高层建筑三维风荷载以及风振响应进行了深入的研究。
     对双塔楼建筑进行了刚性模型风洞试验。在试验结果表达形式上,采用了表面积分法,提出了三维风载合力,便于工程应用。研究了不同风向角下顺风、横风和扭转向的三维风荷载作用,分析了有多塔楼相互干扰的群体体型系数以及局部体型系数。为双塔高层建筑的抗风设计提供了合理的风载取值。
     在双塔楼风洞试验基础上,采用刚性模型表面风压积分法对双塔高层建筑气动力谱进行了研究。分析了顺风、横风和扭转方向前三阶模态力谱,并与单体、简单截面高层建筑模态力谱进行了对比,讨论了各阶振型模态力互谱特性以及顺风—扭转和横风—扭转之间各阶模态力谱相关性。
     应用模态法分析了在邻近塔楼干扰下无弯扭耦联振动的复杂截面塔楼高层建筑风振位移及加速度响应,讨论了顺风、横风和扭转响应随结构不同特性的变化,并对顺风—扭转和横风—扭转加速度响应相关性进行了分析。
     推导了高层建筑在质心和刚心偏心时的三维风振响应公式,讨论了复杂体型双塔建筑在不同偏心情况下对总加速度响应的影响规律,分析了偏心时高阶振型对风振加速度响应的贡献,讨论了偏心时平动—扭转相关性对总加速度响应的影响,最后对复杂体型偏心双塔高层建筑进行了时程风振响应分析。
Along with the development of science and technology, the height of tall building increases constantly. Light and stiff building materials were used widely and at the same time there is lots of twin-tower or multi-tower tall building with complexity shape. Now investigation on wind reduced response of single tall building is gradually popular and there is little investigation on twin-tower or multi-tower tall building with complexity shape. Three-dimensional wind load and wind reduced response of twin-tower tall building with complexity shape are analyzed based on the Xiao Shan International Trade building in the paper.A wind tunnel test for twin-tower tall building rigid model is investigated and the results are gained using surface integral for engineering application convenient. Three-dimensional wind loads including along-wind, across-wind load and torsion moment under different wind direction are mainly discussed and interfering shape coefficient due to adjacent tower tall building and local shape coefficient are analyzed. Reasonable wind loads is provided for the design of wind resistance of twin-tower building.Based on the wind tunnel test, aerodynamic modal force spectrums of twin-tower tall building are studied using surface integral method of rigid model. Modal force spectrum of along wind and across wind and torsion including three modes are analyzed and compared with modal force spectrum of single tall building which are provided by literature. Modal force cross-spectrum and modal force correlation between along-torsion and cross-torsion are discussed under different mode.Wind induced displacement and acceleration response of twin-tower tall building having lateral-torsional uncoupled are analyzed using modal analyses method. The contribution of wind load's statistic correlation for total response is analyzed. Then the structural parameter and interfering of adjacent tall building effect on wind induced response are discussed.The wind induced response formula of tall buildings having no mass and stiffness centre is deduced. The rule of wind induced acceleration response is researched when mass and stiffness centre be at different position. The high mode effect on wind induced acceleration response is analyzed. Wind load's correction
    
    arose from lateral-torsional coupled are discussed. Finally, the wind induced response is analyzed in time domain method.
