1. Section Optimization Competition

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

5. Baseline response

6. Ben Schafer entrant A = 1.088 in 2 My = Mcr = Mcrd = Mcre (96 in.) = Mne = Mn = Mnd = Mn = Yes 151 kip-in. 136 kip-in. 95 kip-in. 140 kip-in. 118 kip-in. 105 kip-in. 99 kip-in. Comment: 9x3x0.5 C-section – nothing fancy

7. Competition You (and your computer partners) have until xxx pm to develop the best beam you can. Key constraints –A must be within 1% of 1.088 in 2 –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...
