A 40 ft simple span beam is loaded with a uniform dead load of 2.4 kips/ft plus the beam self-weight and a uniform live load of 3.3 kips/ft. The lateral supports are located at the supports and at the midpoint of the span. Determine the leastweight W-shape to carry the load. Use A992 steel and Cb= 1.0. Design by (a) LRFD and (b) ASD.

A simply supported beam with a span of 26 FT is used to carry a service dead load (including self-weight) of 1.65 KLF and a service live load of 3.3 KLF and is reinforced with 4-#9 bars. The beam has a width b of 14 IN, an effective depth of 24.5 IN., and a height of 27 IN. The material strengths are f’c = 4000 PSI and fy = 60 KSI. The immediate deflection due to live load is limited...

A one-way solid concrete slab is to be used for a simple span of 18 ft. In addition to its own weight, the slab carries a superimposed dead load of 50 psf and a live load of 75 psf. Using the strength method with f ′c = 4 ksi and fy = 60 ksi, design the slab for minimum overall thickness. (account for weight of slab)
