Forms are being designed for a 12-ft high concrete wall with 2 spans to be poured at a rate of 5 ft/hr, Internally vibrated, at a temperature of 85F. The concrete mixture will use Type 1 Cement with retarders and is estimated to weigh 150 pcf. Sheathing will be 1x12” lumber. Studs will consist of 2x6” and double wales will be 2x4” lumber. Snap ties are 2500-lb capacity. Deflection must not exceed l/240. Use California redwood. Do not use 7 day or wet scenario. a. Determine maximum stud spacing b. Determine maximum double wale spacing c. Determine maximum tie spacing.
Give full explanation Awall form 14 ft high is filled with 160 lb per cu ft concrete at a tem perature of 70°F. The concrete is Type I without a retarder. Concrete will be placed with normal internal vibration to a depth of less than 4 ft. The rate of placement is 5 ft per hr. From Table 1, the value of Cw is 1.1 and from Table 2 the value of Cc is 1.0. The rate of placement is less than 7 ft per hr and the place ment height does not exceed 14 ft so calculate the lateral pressure by using appropriate formula.
