Wind Load Analysis of Roofing System in Luzon, Philippines

Abstract

The Philippines is one of the world's top disaster hotspots because of its vulnerability to numerous natural and man-made dangers. To create efficient risk reduction measures, a systematic vulnerability assessment of important building typologies should be carried out. The roof serves as more than just a covering for our heads; it also serves as the structure's spine or backbone, shielding the house's vital organs. The function of a structure and the roofing materials available determine a roof's features. Flat roof, Gable, Pyramid Hip, Skillion and Lean, Hip and Valley are a few examples of roofing types. The most popular type is long-span, pre-painted metal roofing made of GI sheets. You can also use other metals like copper, tin, and aluminum. The type of roofing system installed on low-rise residential buildings had little to no impact on the intensity of wind loads. The building's location and the roof angle are the only factors that can change the wind pressure. Any roof system will react most strongly at a critical roof angle of 20° where uplift pressure is present.
