Capstone Design Project

A small steel-framed building bay, designed end-to-end with AISC 360-22 LRFD.

Phases

1. 1. Project brief

   Single-story office bay, 30 ft × 30 ft, 14 ft column height. Roof live load 20 psf, snow 25 psf, dead load 25 psf (deck + roofing + MEP). Design per AISC 360-22 LRFD and ASCE 7.

2. 2. Floor plan

   Lay out two girders spanning 30 ft and three infill beams at 10 ft o.c. Place four columns at the bay corners. Provide a small framing-plan sketch.

3. 3. Gravity loads

   Compute tributary loads on each beam, girder, and column. Apply 1.2D + 1.6L (and 1.2D + 1.6S where it controls). Tabulate Pu, Vu, Mu for each member.

4. 4. Beam design

   Select W-shape infill beams using AISC §F2. Check flexure, shear (§G), and serviceability deflection L/360 (live) and L/240 (total). Module 6, 7, 18.

5. 5. Girder design

   Select girders with concentrated loads from the infill beams. Check Cb at point loads, web local yielding/crippling at reactions.

6. 6. Column design

   Choose a W or HSS column. Compute φcPn using AISC §E3. If a moment is collected, check beam-column interaction per §H1.1 (Module 9).

7. 7. Connection selection

   Choose shear connections (Module 14): bolted double-angle or shear tab. Specify bolts per §J3, welds per §J2.

8. 8. Base plate

   Design a column base plate and anchor rods using AISC §J8 and Design Guide 1 (Module 16).

9. 9. Final report

   Compile a clean calculation report: cover, framing plan, load takeoffs, member checks with AISC refs, connection sketches, base plate, materials list.

10. 10. Presentation

    Prepare 8–10 slides: design philosophy, framing, governing checks, connection types, lessons learned.
