This paper presents influence of interfering structures on deformation of cooling tower due to non-axisymmetric horizontal wind loads. First, the pattern of the wind load distribution on cooling tower has been studied in a wind tunnel on 1:150 geometrical scale models with interfering structures, then deformation pattern of the tower have been studied. Wind loads on cooling tower have been obtained under a simulated wind condition for open country and suburban terrain in a Boundary Layer Wind Tunnel at Indian Institute of Technology Roorkee, India. Experimental results show that, in case of interference for an oblique approach wind, there is a significant increase in the magnitude of the net pressure coefficients on windward meridian. Using the experimental wind load values, numerical linear analysis was performed to find the deformation of the tower. The deformations of the tower have evaluated for both mean and fluctuating wind loads. Due to mean wind loads, the maximum deformation occurred at throat level for isolated tower. Also, the fluctuating wind load shows no significant adverse change in the deformation for the interference condition where magnitude of wind loads enhanced significantly as compare to isolated tower.
