Building tower crown mounting method for overcoming wind-induced vibration
The invention relates to the technical field of on-site preparation, carrying or processing of building materials or building components, and discloses a building tower crown installation method for overcoming wind-induced vibration, column periphery inhaul cables are arranged on the periphery of a main column to resist bending of the main column, so that the main column shows the characteristic of a rigid structure, and when wind-induced vibration occurs, the main column is provided with a plurality of stay ropes, the position with the largest amplitude is fixed, and then the tuned mass damper is installed at the position with the largest amplitude, so that the damper can play a role more effectively, and the needed size and self weight are greatly reduced; due to the fact that the dampers are small and light, two sets of energy consumption systems aiming at low-frequency vibration of the main column are built through the prestressed inhaul cables and components of the tower crown, it is guaranteed that the building tower crown can resist wind on the premise that the weight is not increased, the whole building tower crown is very light, the annular riding track and the dampers are allowed to be preset in the main column, and the main column is hoisted in a segmented mode; and then the annular riding track and the guardrails of the annular riding track are used as an operation platform, and an aerial work platform and a protection structure do not need to be additionally built.
本发明涉及建筑材料或建筑构件在现场的制备，搬运或加工技术领域，公开了一种用于克服风致振动的建筑塔冠安装方法，通过在主柱一周设置柱周拉索抵抗主柱的弯曲，使得主柱表现出刚性结构的特征，在风致振动发生时，振幅最大的位置固定，然后在振幅最大的位置安装调谐质量阻尼器，从而使得阻尼器能够更有效地发挥作用，所需的体积及自重大幅减小；由于阻尼器小且轻，且利用预应力拉索及塔冠本身的构件搭建了两套分别针对主柱低频振动的耗能体系，在不增重的前提下确保建筑塔冠能够抗风，整个建筑塔冠非常轻，允许将环状马道及阻尼器预置在主柱中并分段吊装主柱，然后利用环状马道及其护栏作为作业平台，无需额外搭建高空作业平台及防护结构。
