WIND LOADS ON MULTI NATURAL DRAFT COOLING TOWERS IN A POWER PLANT
某电厂自然通风冷却塔塔群风载荷研究

Natural draft cooling tower is a high-rise thin shell structure. The displacement in the top of the cooling tower can be tens of centimeters under wind loads, several times of the wall thickness. Cooling tower is very sensitive to wind loads, especially in multi-towers conditions, where the wind velocity, wind pressure distribution and airflow among towers are quite complex. On the basis of the experiment results on irregular multi-towers, this paper put forward some proposals about determining wind loads of natural draft cooling tower in multi- towers conditions.
