高层建筑结构主要受水平荷载作用的控制,其高度越高,水平荷载的影响越大。水平荷载通常有风荷载和地震作用。这两种水平荷载对高层建筑结构的要求,有时可能是相互矛盾的。在风荷载作用下,高层建筑结构会发生侧移,侧移值的大小与风荷载值、高层建筑的总刚度有关,当风压一定时,高层建筑的总刚度越小,产生的侧移越大。当侧移过大时,会在房屋的使用上和人的感觉上发生问题。还
The structure of high-rise buildings is mainly controlled by horizontal load. The higher the height, the greater the influence of horizontal load. Horizontal loads usually have wind loads and earthquakes. The requirements of these two horizontal loads on the tall buildings can sometimes be contradictory. Under the action of wind load, the lateral displacement of high-rise buildings occurs. The magnitude of lateral displacement is related to the wind load value and the total stiffness of the tall buildings. When the wind pressure is constant, the total stiffness of the tall buildings is smaller and the lateral displacement Big. When the side is shifted too much, problems can arise with the use of the house and with people’s feelings. also
