For hurricane strapping of roof trusses in Hawaii, what is the minimum required connection capacity for each truss-to-wall connection?
Correct Answer
B) 1,500 lbs uplift
Hawaii requires minimum 1,500 lbs uplift resistance for each truss-to-wall connection to resist hurricane-force winds, significantly higher than mainland requirements.
Why This Is the Correct Answer
Hawaii requires a minimum of 1,500 lbs uplift resistance for each truss-to-wall connection. This requirement reflects Hawaii's vulnerability to powerful hurricanes and tropical storms, where wind-induced uplift forces can easily exceed the capacities required by mainland codes. The 1,500 lb threshold ensures roof systems remain attached to wall framing during extreme wind events.
Why the Other Options Are Wrong
Option A: 750 lbs uplift
750 lbs uplift is approximately half of Hawaii's requirement. This level of resistance might be sufficient in lower wind regions but does not meet the standard for Hawaii's hurricane exposure.
Option C: 1,000 lbs uplift
1,000 lbs uplift is a reasonable but insufficient answer for Hawaii. It exceeds many mainland requirements but falls short of the 1,500 lb minimum mandated by Hawaii's enhanced wind provisions.
Option D: 500 lbs uplift
500 lbs uplift is far below Hawaii's standard. This is the approximate capacity of very light strap hardware and is not suitable for hurricane-zone roof-to-wall connections.
Memory Technique
1,500 lbs is Hawaii's magic number for wind connections. Visualize a hurricane strap holding 1,500 one-pound bags of sand — that's the force it must resist. Fifteen hundred = 'Hawaii's fifteen hundred rule.'
