What is the preferred preliminary measure of hurricane intensity? A. Modified Mercalli Intensity scale, B. "mean recurrence interval" or "return period" of 50-year storm, C. Saffir-Simpson scale, D. Richter scale

From this plan of a simple wood frame structure (1-story height), what is the maximum chord force at the east and west edges of the roof diaphragm if 110 lbs/foot lateral wind load is exerted as shown? A. 18,340 lbs B. 367 lbs C. 3,670 lbs D. 4,600 lbs Answer D. 4,600 is correct. The lateral wind load here is similar to a uniform load acting on a simple beam turned on its side. To find the maximum chord force at the edges of the diaphragm, use the equation for maximum moment wl²/8 ÷ building plan depth. 110 lbs per foot x (100 ft)² / 8 ÷ 30ft = 4,583.33 ARE 4.0 exam prep: SS

Wind exerts pressure (i.e. positive, negative) on different building surface conditions. This diagram shows positive pressure on the windward vertical and normal to windward roof surfaces. Which condition is indicated? A. roof slope up to 7:12 B. roof slope greater than 7:12 C. flat roof Answer B. roof slope greater than 7:12 (negative pressure or suction is exerted on the leeward side of both 7:12 slopes).

In which type of climate would a staggered building layout be most appropriate? A. hot-arid B. cold C. temperate D. hot-humid Answer D. hot-humid. A staggered layout promotes air flow and ventilation between buildings. ARE 4.0 exam prep: SPD

What is the benefit with regard to wind forces for tall buildings whose form becomes tapered as it rises? Answer As the floor plates and building shape tapers at upper levels, less exposed surface area is subjected to intensifying wind pressures and wind velocity.
