A flat roof is subject to the following uniformly distributed loads: a dead load of 33 psf (pounds per square foot of roof surface), a roof live load of 13 psf, a snow load of 17 psf, and a wind load of 26 psf downward. If ASD is used, determine the required load capacity (required strength), Ra.

A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 64 ft-kips, and the maximum moment for the service live load is 55 ft-kips (these moments occur at the same location on the beam and can therefore be combined). If ASD is used, what is the required nominal strength of the beam for a safety factor Ω of 1.70?
