| Abstract | Industrial buildings are generally provided with sloping roofs in order to achieve large column free areas. It is noticed that roofs of many of such buildings are blown off during cyclonic storms. Whereas one of the possible reasons may be improper construction, another reason may be under estimation of wind loads acting on them. Structural designers generally refer to standards on wind loads of different countries to choose suitable values of wind pressure coefficients acting on sloping roofs. However, values of wind pressure coefficients available in literature are limited to certain roof slopes and certain wind incidence angles only. An attempt has, therefore, been made to carry out experimental study on the models of industrial building with north-light roof in order to generate more information about wind pressure distribution on it. The models are tested in a closed circuit boundary layer wind tunnel to measure values of wind pressures on roof surface. Four cases namely one, two, three and four spans are considered. Plywood models are placed by the side of Perspex sheet model in case of multi-span study. Wind is made to hit the models at 13 wind incidence angles from 0 |
