2. DESIGN a simply supported, fully braced, Douglas Fir-Larch North Construction Grade (7 days load)- JOISTS to support a uniform load, w = 140 PLF and which has a length, L = 12 Ft as shown in the sketch above. Three floor joists will be spaced at sixteen (16") inches on center CONNECTED BY DECKING. Moisture is more than 19% and temperature 101F. WET Conditions. Check your design for bending, deflection and shear criteria only. Begin with 2X sizes when determining a trial section and proceed to 3X sizes only if necessary. Calculate the maximum deflection that the beam experiences at mid-span. Neglect the weight of the joist. The allowable deflection per the Florida Building Code is all = l/240. Assume Cf = 1.0 and Cfu = 1.2. Show all calculations. HINT #1: max = 5WL3 /384EI. HINT #2: Mmax = wL2 /8; Vmax = wL/2; SREQ = Mmax/F'b; fv=1.5(Vmax/bd)
