Wind Pressure Distribution on Domical Roofs

Astha Verma, Ashok K. Ahuja

Present paper describes the details of the experimental study carried out on the models of low-rise buildings with domical roofs. Wind pressure measurements are made on rigid models by placing them in an open circuit boundary layer wind tunnel. The study includes square and rectangular plan buildings with one and two domes respectively. The experimental results of pressure measurements are reported in the form of contours of mean wind pressure coefficients on the surfaces of domes. Results presented in the paper are of great use for the structural designers while designing buildings with domical roofs. The experts responsible for revising wind-loading codes from time to time can also use these values.
