Question: 1. Calculate the maximum allowable span for 3/4-in. (19-mm) Class I Ply form decking with face grain across supports carrying a design load of 150 lb/sq ft (7.2 kPa). Assume that the decking is continuous over three or more spans and limit deflection to ½40 of span length.
2. What loads must formwork for elevated slabs be designed to resist?
3. What should be the design load for a column form 18 ft (5.5 m) high that is to be filled by pumping concrete weighing 150 lb/cu ft (2403 kg/m3) from the bottom?
