【摘要】 近年来,国内外超高层建筑不断涌现,风荷载作为一种典型的水平向动力荷载引起了国内外学者的广泛关注。目前,对超高层建筑的风振响应分析大多以整体结构为研究对象,较少针对施工期的建筑结构进行研究。本文以一实际超高层框筒结构工程为例,建立结构三维精细化有限元模型,考虑施工过程和混凝土时变性因素的影响,对结构进行了施工期风振响应分析。通过研究,得到了该超高层框筒结构的加速度、节点位移及层间位移角随施工过程的变化规律,研究成果具有一定的参考价值。更多还原

【Abstract】 In recent years,domestic and foreign high-rise buildings continue to emerge,the wind load as a typical horizontal dynamic load caused widespread concern of scholars at home and abroad. At present,the study on the wind-induced vibration response of super high-rise buildings takes the whole structure as the research object,and the research on the building structure is less. In this paper,taking an actual high-rise frame tube structure engineering as an example,the establishment of three-dimensional fine finite element model,considering the influence factors of degeneration of construction process and concrete, the wind vibration response analysis of structure during construction. Based on the research,the variation law of acceleration,displacement and story drift angle of the super tall frame tube structure is obtained.更多还原
