What does FM 1-90 address?

• A. Criteria for structural design, live loads, and uplift for roof decks.
• B. Fire resistance of roofs.
• C. Color options for roofing.
• D. Maintenance schedules.

Answer: (A)

FM 1-90 addresses how roof decks are designed to resist structural loads, including live loads and wind uplift. It provides criteria that engineers use to size decking, fasteners, and connections so the roof system can withstand the expected forces without failure. This is about structural capability and performance under actual use and wind conditions, not aesthetics or maintenance. Fire resistance is governed by separate fire-rating standards, while color options and maintenance schedules lie outside the scope of structural design criteria.
