Design Summary
Typical Sequence
1. use bending to estimate size of beam
required S = M/F'b or Mu/F'bn
CE 110 examples: 8.38, 8.39, 8.39 video
2. check shear
revise beam size if unsatisfactory (required A = 1.5V/F'v)
3. check deflection
revise beam size if unsatisfactory
Most Economical (in homework)
satisfy bending, shear and deflection with minimum A
board foot = 1" x 12" x 12"
Other Sizing Considerations
1. detailing (fit in the structure, connect to other members)
2. uniformity with other members (convenient for detailing, ordering and construction)
3. availability of sizes and grades
