摘要
采用我国沿海区域由北到南三个典型区域的台风风场,以某超大型冷却塔为原型进行单塔测压和测振试验,得到台风和规范风下冷却塔的平均风压分布和风振系数等风荷载参数。将该超大型冷却塔在台风和规范风荷载作用下的内力进行比较,发现规范风荷载下的内力可完全包络台风荷载下的内力,说明按规范风进行冷却塔结构设计可保证在台风作用下的安全性。
Adopting Chinese three typical coastal areas＇ typhoon fields from north to south, taking a super large cooling tower as the prototype, wind tunnel tests of pressure and vibration measurement for single tower are carried out, and average wind pressure distribution and wind induced vibration coefficient for tower under typhoon and wind load in code are got. The super large cooling tower＇s internal forces under typhoon loads and wind loads in code are compared. It can be found that the internal forces under typhoon loads can be completely enveloped by the internal forces under wind loads in code, indicating that the cooling tower＇s safety under typhoon loads can be guaranteed if the tower structure is designed according .to the wind loads in code.
