. Forms are being designed for an 10 ft high concrete wall to be poured at the rate of 5 ft/hr, internally vibrated, at 95 degree temperature. The concrete mixture will use Type I cement w/o retarders and estimated to weight 150 pcf. Sheathing will be 7/8 inch thick Class 1 Plyform with face grain perpendicular to studs. Studs and will be 2 x 6 in lumber. Double wales will be 3 x 4 in lumber Snap ties are 2,500 lb capacity with 12 in wide wedges bearing on wales. Deflection must not exceed 1/360. Allowable stresses for lumber being used for studs and wales are: Allowable stresses for studs an wales are: Fb = 1,750 psi Fv = 130 psi Fcl = 495 psi E = 1.6 x 106 psi . . 10 ft 8 ft 6 ft . Bracing Design: Determine the maximum spacing of 2 x 4 in previous example Assume the local code wind requirements are less stringent than Table 13-3. Allowable stress values for braces are o E= 1.5 x 106 psi o Fc = 850 psi o Ft = 725 psi Determine the stud, wales, tie, and braces spacing. .
