2. A continuous concrete floor system consists of parallel beams spaced 8' on centers and spanning 25' between supports. The 4" thick slab is cast monolithically with the beam webs which have width, b 14 in. and total depth h 28 in. (measured from top of slab). Each T- beam must carry a dead load of 55 psf (the slab weight+ flooring) and service live load of 225 psf in addition to its own weight. Material properties are fe-4 ksi...
A simply supported beam as shown in the figure. The beam section is W18x211. The beam must support its own weight and must carry the following loading: Super-imposed distributed dead load = 0.25 kip/ft Distributed live load = 1 kip/ft Concentrated dead load = 12 kip The beam span L = 26 ft and the distance of the concentrated load from the right support a=6 ft. Consider analy- sis of beam subjected to load combination 1.2 dead + 1.6 live....

Assume that the floor between Beams B7 and B8 is supported
directly by these two beams only (not by Girders G2 and G3). Beam
B7 has a self-weight of 30 plf. The floor slab consists of a
4-in.-thick, normal-weight, reinforced concrete slab (unit weight =
150 pcf). An additional floor dead load of 15 psf is specified to
account for the weight of suspended utilities and fixtures. As an
exterior beam, B7 must also support one...

Check the adequacy of a W18X35 for a beam (the beam in the vertical direction in the plan) in a floor framing system in terms of 1) bending strength; 2) shear strength and 3) deflection. The beams support a 4-inch-thick reinforced concreted floor slab (with a density of 150 lbs/ft?). Besides the weight of the structure, loads consist of a uniform live load of 80 psf and moveable partitions (with a uniformly distributed load of 20 psf of floor surface)....
Could you please help me on question 7.

1. T-Beams are used to support a floor in an industrial building. The floor is used for product storage so it must be designed for a heavy 600 psf. The floor must also support a superimposed dead load of 20 psf (in addition to the self-weight of the beams and slab. The layout of the beams and slabs is shown below. The beams span 30.0% and are spaced at 4.0” center to center. The slab is 3” thick. The concrete...

4. A composite floor system consists of a 5-inch slab which is supported by W14x30 beams without shoring. Fy-50 ksi, strength of concrete is 4ksi, beam spacing is 8-ft, the effective width is 81-inches, and the span is 35-ft. Construction load is 20 psf and the live load is 160 psf. Compute the maximum deflection before the concrete has cured. (credit weight 20)
