【摘要】：以深圳平安金融中心为工程背景,对其进行重力荷载作用下的长期变形分析。考虑混凝土收缩徐变以及竖向构件含钢率的影响,按设计标高逐层找平、逐层找正施工模拟,研究超高层建筑重力荷载下长期变形规律,分析不均匀的竖向变形对结构安全的影响。进一步提出在施工中给竖向构件适当预留长度以补偿预计的竖向构件变形的设计思路,实现在设定阶段(如建筑投入使用1年)竖向构件达到设计标高,实现楼面平整,以满足建筑正常使用要求,并对楼层标高预留高度和竖向构件下料预留长度的控制方法进行了分析。研究表明,通过对超高层重力荷载作用下的变形分析与控制,可以掌握结构的长期变形规律,得到构件附加内力,控制楼面标高。
[Abstract]:Taking Ping an Financial Center of Shenzhen as the engineering background, the long-term deformation analysis under gravity load is carried out. Considering the influence of shrinkage and creep of concrete and the steel content of vertical members, leveling is carried out layer by layer according to the design elevation. The long-term deformation law of super high-rise building under gravity load is studied. This paper analyzes the influence of uneven vertical deformation on structural safety and further puts forward the design idea of suitably reserving the length of vertical members in construction to compensate for the predicted deformation of vertical members. The vertical components can reach the design elevation in the setting stage (for example, the building is put into use for one year), and the floor is flat to meet the requirements of the normal use of the building. The control methods of the height of the floor and the length of the vertical component are analyzed. The results show that the deformation analysis and control are carried out under the action of the super high gravity load. The long-term deformation law of the structure can be grasped, the additional internal force of the member can be obtained, and the floor elevation can be controlled.
