Place a 6 3/4" x 16 1/2" ridge beam in the center of the structure 24' from the sidewalls. Specify 6 X 6 wood posts at 20 intervals along this beam with + x 6 posts at the ends hidden in the walls. Specify 4 x 6 or 4 x 4 post at each beam/wall inter- section (hide in wall). Show splices in the ridge beam 48" from the post so that the center beam is only 12' long. Use a 13 1/2" deep beam for the center span. Hang 5 1/8 x 15 glu-lam beams at 15'-0" o.c. on each side of the ridge beam. Hang 3 1/8 x 13 1/2 glu-lams at 8'-0" o.c. between each 15" glu-lam. Support these beams with (2) -2 x 6 at each wall. Hang 2 X 6 ral- ters at 24" o.c. between each 13 1/2" glu-lam with appropriate hangers. Show enough of the roof fram- ing to represent the framing patterns. Provide grids to represent each wall and post so that four vertical and three horizontal grids are provided. Specify the loca- tion of all members. Use a schedule wherever possible. Assume the sheet to be S-502. 0 A B can resist 3500 pounds in uplift. Problem 7-3 Show a 2 x 8 DFL rafter at 24" o.c. with a 12" overhang supporting 1/2" plywood sheathing, and composition shingles at a 6/12 pitch resting on (2)- 2 x 6 top plates resting on 2 × 6 studs at 16" o.c. Use 2 x 6 ceiling joists at 16" o.c. and specify a 1 x 6 fascia. Problem 11-5 Use the attached sketch to draw a section view showing an 8" wide x 48" maximum high retain- ing wall. Support the wall on a 14" deep footing that tapers from 30" to 54". Show the footing extending 8" to 12" at soil side, with a 4" French drain in 8" x 24" x 3/4" gravel bed. Extend the wall 6" minimum above the finish grade. Show a 5" thick slab reinforced with 12/12 x W1.4/W1.4 mesh 3" from top surface over 4" gravel fill. Reinforce the footing with grade 40, #4 @ 8" o.c. each way 3" up/dn. Show a grade 60, #5 @ 10" o.c. x 24" L into footing, with a 400 lap to the vertical wall steel. Reinforce the wall with grade 60, #5 @10" o.c. each way, 2" clear of wall. 2' CUR 36" K RAIL e 720.C W10"EMB. #54@10"0.c/E.W 3 3 " -5" 343 4'GRAVEL 30-54 #54e idd... #4CBOC EAWAY in parte sections aghts, so fund parte cores muy be vappersed to the kandor eChapte Cengt Langens the night to tal como at any tow begot gences engany
