(50 Points) You talk with the owner and he likes the idea of using two large glulam beams as shown to carry the joist loads. Design the glulam beams using stress class 20F- 1.5E glulam material (see Table 5A in the wood supplement handout) and assume 5'-1/8" wide by 25'-1/2" deep glulam beam. Check bending and shear stresses, do not check deflection. If this beam does not work, what are your options to make it work without changing the stress class? Select one of these options and try to make it work. If your second attempt still fails, show your work and move on to Problem 3 after you price your more expensive answer. Pricing for glulam is about $4 per inch of depth per linear foot. For example: For a 25.5" deep beam, price will be $4*25.5" per linear foot $102/linear foot of beam length. Price out your final answer for use in the last problem.
