Enhanced Hurricane Protection Jason Barrocas Kevin Hernandez Tanisha Richard Department of Mechanical Engineering Florida International University - Miami, Florida
Problem • The purpose of this project is to design a retractable dome that could protect a home in the event of a hurricane • The majority of damage is caused by the storm’s intense wind • Hurricane shutters and impact glass protect only the windows
Project Goals • Reduce rebuilding costs • Protect human life • Current advances in technology make it plausible to offer better protection • The retractable roofs of stadiums offer a blueprint for retractable domes
Design Concepts • A dome structure offers the best resistance to lift and drag forces Design Criteria: Ribbed Structure of Protective Dome • Seven arched trusses • Mesh material covering the frame • Reduces wind speed by 60% • Category 5 Hurricane – 155+ mph • Reduces wind speed to a manageable level
Economic Feasibility • Estimated Cost for Enhanced Hurricane Protection • 7 Trusses comprised of W16 X 26 I-Beams: $13,000 • Goal for entire steel frame (trusses, pivots and joints): <$20,000 • Goal for entire dome (parts and labor, fully installed): <$50,000
Current Design • Diameter: 70 ft • Dome Height: 35 ft • Estimated Weight • 7 Steel trusses: 18,000 lb • Frame (trusses, pivots and joints): 28,000 lb • Entire Dome (frame, mechanism and mesh): 33,000 lb
Conclusion • Objective is to achieve substantial hurricane protection • Safer than products on the market now • Prototype Testing • Budget: $2,000 • Wind Testing • FEM Analysis • Structural Analysis • Long term goals • Reduce cost of rebuilding • Future design accommodating apartments and townhouses
