VERTICAL FORMWORK DESIGN HOMEWORK Design formwork for a 6-ft-high wall. The concrete is to be placed at a rate of 2fthr and will not be vibrated. Concrete temperature is expected to be 50∘F. Use standard weight concrete, Type I cement, 3 in. slump, with no admixtures. The maximum allowable deflection of bending members is to be 1/360 of the span. Use 3/4in. class I plyform for the sheathing with face-grain across the supports. Use 2 X 6 Hem-Fir No. 2 for the rest of the lumber and double-wales. Assume all bending members to be supported on three or more spans. Ties available for use have an allowable load of 5000lb. Show all your work.
Given: 6-in. structural concrete floor slab. Use 3/4-in. class I plyform parallel to the span for the sheathing and Southern Yellow Pine #2 for the rest of the lumber. Joists will be 2×8 and stringers will be 6×8. Unsupported height of shores will be 10−ft. and they will be S4S. The maximum deflection for the sheathing may be taken as 1/360 of the span. Motorized buggies will be used to transport the normal weight concrete. Find: Design the formwork for this slab. Solution: Show all your work.
