超高层建筑施工期间侧向变形影响因素的详细分析

Detailed Analysis on the Factors Affecting Lateral Deformation During the Construction of Super High-Rise Buildings

超高层巨型框架核心筒结构体系是新时代工程技术的代表之一,目前关于超高层建筑竖向变形的影响因素已有大量论证,但是施工过程中其相关因素对超高层建筑的横向变形影响如何尚未可知,因此文章以保定源盛水岸国际项目巨型框架核心筒超高层结构为工程背景,通过考虑混凝土的时变特性、风的作用机理及施工设备影响,对建筑结构在施工阶段的水平位移进行了研究分析,得出结论,在超高层建筑结构侧向位移分析中,风荷载对结构在施工阶段侧向位移的影响最大,其次是运输设备的水平荷载。

The super-high-rise mega-frame core-tube structure system is one of the representatives of the engineering technology in this new era.However,although there are a lot of arguments about the factors influencing the vertical deformation of super high-rise buildings,the influence of related factors on the lateral deformation of super high-rise buildings during the construction process is not yet known.Therefore,this paper takes the super-high-rise structure with mega-frame core tube in Yuansheng Shui’an of Baoding as the engineering background,considers the time-varying characteristics of concrete,the mechanism of wind and the influence of construction equipment,and then studies and analyzes the horizontal displacement of building structure in the construction stage.It is concluded that in the lateral displacement of super high-rise building,the wind load has the most influence on the lateral displacement of the structure during construction,followed by the horizontal load of transport equipment.
