- Abstract
- Wind pressures measured on a 1:80 scale model of the RP-US Bayanihan Permanent School Building are compared with wind pressures used in the original design calculations. The wind tunnel studies were conducted in a tunnel fitted with spires and roughness elements to generate a thick, turbulent boundary layer. This boundary layer is believed to be a reasonable simulation of the lowest portion of the atmospheric surface layer developed over rolling countryside with scattered trees or over suburban areas. While the wind tunnel test results are in fair agreement with the overall design wind pressures, edges of the roof along the end walls can be subjected to pressures which substantially exceed the design values. It is recommended that the load capacity of certain roof elements be reexamined and that ridge ventilators be used in future construction to reduce the uplift loads on the roof structure.
