  1. Section Optimization Competition

  2. Baseline model • C-section • 9 in. web, 3 in. flange, ½ in. lips t=0.068 in. • fy = 50 ksi • A = 1.088 in2 • My = 151 kip-in. • Loading and conditions • pure flexural loading (beam) – pin supports • braced at 96 in.

  3. Baseline response

  4. A = 1.088 in2 My = Mcrl = Mcrd = Mcre (96 in.) = Mne = Mnl = Mnd = Mn = Yes 151 kip-in. 136 kip-in. 95 kip-in. 140 kip-in. 118 kip-in. 105 kip-in. 99 kip-in. 99 kip-in. Ben Schafer entrant Comment: 9x3x0.5 C-section – nothing fancy

  5. Competition • You (and your computer partners) have untilxxx pm to develop the best beam you can. • Key constraints • A must be within 1% of 1.088 in2 • Mcre is taken at 96 in., fy=50 ksi • When you have a beam you would like to enter on the big board, let me know. • Raise your hands or speak up if you have any questions...
