All work must be shown. You are in charge of retrofitting an existing building. The columns and girders are in place, and you have to design the beams. The building is high end (deflection limited to live load limit of L/480 and a dead load+ live load requirement of L/240). Design the most economical beam size (using conservative calculations) if the unfactored live load is 100 psf and the unfactored dead load (including beam weight) is 80 psf 30 Points...

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...

loads (no load factors or impact).
(Stringer Calculations – Pedestrian Loading)
1. Calculate all dead
and live loads.
2. Calculate the maximum
reactions for the exterior and interior stringers.

Select reinforcement for the T-beams in the simply-supported floor system shown below. The system is 26-foot-long and subjected to its own self-weight and a service live load of 200 psf. Take the compressive strength of the concrete to be fe' = 3 ksi and the yield stress of the rebar to be fy = 60 ksi. Show a sketch of the designed cross-section, including beam dimensions and reinforcement selection. Limit your reinforcement selection to one that incorporates a single layer...
