Description/Paper Instructions
Structural Steel Design Paper
1) using elastic design, select an adequate wide flange for all the highlighted (in red) members. write your selection right over the member (like on the beams along grid 1) -use asd or lrfd, your choice. remember that lrfd is less conservative. -see notes from the project manager in the next page. -show your calcs for every beam. -extra credits (hw_pointsx1.2): design the entire framing plan.

Remember that after you make sure that your beam is safe, you should check that your deflections stays below L/360 under live load and below L/240 under total load, at minimum. NOTE: Do not factor the loads when you compute deflection.
notes from project manager: general note: we have height restrictions on the floor below, please keep the beams depth as shallow
as possible and strictly under 16.1 inches. also, mind at budget and always try to choose the most economical shape.
note a: please limit the size of this beam to w10, w12 max; also, we are attaching a fancy facade to this beam, the manufacturer told me that this beam cannot deflect more than 1/2″ or the facade will crack.
note b: please mind that i am trying to hide this beam in the partition wall (7 1/2″ thick). see sketch

– Use this page to write your calculations (you can print this page multiple times) – No messy calcs. Don’t forget dimensions.

2) Look at note A, without the height restriction, what would be the most efficient shape to use in this case? Write a note to your project manager, explaining why you had to select a heavy wide flange, explain what stiffness is, and the role of the moment of inertia in this selection (your project manager did not take a steel design class).
3) Look at note B, use both ASD and LRFD to select this shape. Do you feel LRFD helps you better meeting all the restrictions? Why?
4) In your own words, describe the behavior of the cross section below when subjected to a point load as shown. Make sure to indicate tension and compression, explain the stress distribution and don’t forget to mention the role of the moment of inertia. Feel free to get aided by formulas, sketches and diagrams.
