Description:
"During windstorms, such as hurricanes, roofs are subjected to high wind uplift pressure, especially at the edges and corners. Such wind loading often causes damage to conventional roofing systems. Roof damage can lead to water intrusion, causing serious impairment to building interiors and contents. The objective of this research is to develop a new roof system for commercial and industrial buildings that withstands high wind pressures and resist hurricane induced damage. The proposed system includes prefabricated panels using high performance concrete and non-corrosive reinforcement and addresses the structural and architectural requirements. The effort is to improve the structural efficiency while reducing the weight of the system. A comprehensive test plan has been established. A finite element model of the roofing system will be developed and validated through the experimental results.
The proposed roof system will make significant contributions towards enhancing the hurricane resilience of buildings in vulnerable coastal communities. It would be lightweight, wind resistant, durable, non-corrosive, and almost maintenance-free with low risk of damage from fungi and termites. The system is applicable to new construction as well as upgrading the roof of existing buildings. The estimated cost is comparable to the cost of conventional roofing systems."
