Abstract: Support system of an air cooled condenser is a new type structure in thermal power plant,whose body shape is complex. Under structure are big diameter reinforced concrete pipe columns,up the structure is spatial steel truss with wind wall,and on the platform are air cooled condenser equipments. At present,wind load parameters of this kind of structure are not covered in present wind load code,the technical code for the design of civil structure of fossil-fuel power plant just gives the wind wall’s body coefficient. As the air cooled condenser equipment is an air permeability structure,when wind resistance design of the structure,the determination of the wind load body coefficient of air cooled condenser equipment lacks theoretical basis and has no reference,some wind parameters are not reasonable. According to the characters of the structures,a rigid model wind tunnel test and numerical simulation were carried out to study the pressure distribution rule and obtain the wind parameters of the structure. The accurate confirmation of cooled condenser equipment’s body coefficient under different conditions has important guiding meanings for the wind resistance design of this kind of structure.
