Determine if a 10-ft. long 6 x14 beam is adequate to support a dead load wD= 0.3 kip/ft. and a live load wL= 0.4 kip/ft. The member is unincised-No 1 Hem-Fir with MC > 19% and a normal temperature range. Live load deflection should not exceed L/360 and total deflection should not exceed L/240. The member is part of a floor system and is repeated every 26-in. It is also fully braced by the floor sheathing and sits on a 4-in wide beam (nominal) on each side. Make sure you check all limit states even if the first one you check shows the beam to be inadequate.

А w18 x 40 steel spandrel (edge) beam spans 20'. The beam supports a uniform floor live load of 1 kip/ft and a uniform floor dead load of 0.5 kip/ft. The beam also supports brick veneer weighing .6 kip/ft as a uniform dead load. The maximum allowable total load deflection for beams supporting masonry (brick or block) is L/640. Calculate the live load and total load deflections. Do the live load and total load deflections exceed the allowable deflections for...
Q3) A simply supported beam is subjected to a uniform service dead load of 2.3 kips/ft (excluding the weight of the beam), a uniform service live load of 3.0 kips/ft. The beam is 30 feet long, and deflection not to exceed L/360. The beam has continuous lateral support, and A992 steel is used. Is a W27 x 84 adequate?
The beam below is braced laterally only at the reactions and the point of the load. The point load consists of a 34-kip dead and 62-kip live load.

Please refer AISC 15th edition 3. A simply supported beam (W18x97) is 50-ft long and is restrained at the supports and at midspan. It carries a uniform dead load of 0.4 kips/ft plus beam weight, and a live load of 1.0 kips/ft. The steel is A992 and the method of analysis is LRFD. Determine if this shape and length is adequate to support this load. Also determine which controls: flexural strength or deflection. The limiting maximum live load deflection is...
