unit 3.2.6
In this activity you will design floor framing (beams and girders) for a hotel
1. If the beam loading and beam span is different for every beam in a building, is it reasonable and practical to choose a different beam section for every installation? Why or why not?
But It's cheaper using different sized beams, but easier using one beam per area.
2. Aside from simply pushing the wrong keys on your calculator, what is the most likely reason for an error in calculating a required section modulus or a deflection?
Using wrong values on the chart
3. Which structural steel section would carry the largest bending moment, a W12 x 22 or a W14 x 22? Why? If subjected to the same magnitude of loading over the same span, which beam would display the largest deflection? Why?
W14x22
