1. The floor framing plan is shown below. Design the beams B1, B2, and Ba Check the beam weight for each beam. The bay does not repeat. Note The dead load does not include the weight of the beam Select the most economical section for each design to be fully laterally braced. Use A36 steel where Beam B1 frames into it only.

6. The figure below shows the floor framing plan for an office building. The roof has the same framing plan as the floor. Select a W12 section for Column C1 in the first floor and assume the same column will be used for Column C2 in the second floor. Floor loads (applied on the 2 floor; dead load of 200 psf and live load of 300 psf Roof loads (applied on the roof: dead load of 100 psf and roof...

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...

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...

General Information (Problems 2–4) The envelope of a four-story steel building (risk category II) is shown below. Resistance to lateral loads (wind and earthquake) in the direction shown is provided by a steel braced frame on the interior of the building. The gravity load system, floor and roof diaphragms, and the lateral load system for the orthogonal direction are omitted from the figure. GRAVITY BF Roof 15 ft - - - - - - 15 ft WIND 3 15 ft...
