In LRFD, the load factor for the rain load in load combination 2 is ____.

What does LRFD stand for?

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?

A 1/2 in. x 10.0 in. plate is connected to a gusset with six 1/2 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A36: Fy = 36 ksi, Fu = 58 ksi. Assume that Ae = An. Compute the design strength for LRFD.

Plain carbon steels have higher strength and lower ductility than low-alloy steels.

Allowable stress design is also known as plastic design.

Which formula represents Hooke’s law?

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 1.000 inch. Two marks were made along the length of the specimen and were measured to be 2.850 inches apart. This distance is defined as the gage length, and all length measurements were made between the two marks. The specimen was loaded to failure. Fracture occurred at a load of 29,000 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.583 inch and 3.141 inches. Determine the elongation as a percentage.

The fundamental requirement of structural design is that required strength is _______ available strength.
