For the following loading diagram, determine the most economical size based upon the loading diagram. Apply the bending coerricitent and then determine the required sized based upon the effective moment. Loads are unfactored and the beam weight is included in the unit weights.

A three-story building has a floor layout as shown in Figure 1 with 30 ft bays in each direction. It must support a uniform dead load of 90 psf and a uniform live load of 80 psf. For LRFD design, determine the required moment and shear strength for beams and required axial strength for columns indicated below. In the calculations, assume all beams and girders are simply supported. a) The beam marked with #1 if the deck spans from line...

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...
seeking structural engineering help. please answer the entire
question, showing all steps. thank you very much!
The structural steel framing plan of the figure represents a floor system for a narrow commercial building. The floor is to support a 6 in. thick reinforced concrete slab, a live load of 150 psf and an additional future load of 20 psf. Use the Allowable Stress Design (as per the class reference materials) and ASTMA36 steel for all members, use 0.6 Fy as...
