Question: Due Date: Name: A 2 0 i n . square column 1 2 f t high is to be concreted in 1 h r at

Due Date:
Name:
A 20in. square column 12ft high is to be concreted in 1hr at temperature of 60F. Use Tables and Design the formwork (sheathing, studs and clamps) for ten or more uses, with 34-in. plywood sheathing braced by 24's of construction grade Douglas Fir-Larch used flat and clamped with metal "self-squaring" clamps. (10 points)
Use Tables and out spacing of supports for sheathing, joists, and stringers components of slab formwork using tables. The total dead and live load including the self weight of the slab acting on sheathing is 355 psf. Use 2x4 S4S for joists and stringers. Use #2 Douglas Fir Larch species. Use 34 inch plywood for sheathing. Assume all supports as continuous over four or more supports. Assume grains parallel to span. Assume forms are not reused. (10 points)
Use the tables to determine spacing of wall form members, assuming continuing reuse of the forms and No.2 grade Douglas Fir-Larch or equal lumber, with sheathing of Plyform class I plywood. Design a 10ft high wall form for a maximum lateral pressure of 600psf, assuming no reduction of pressure near the top of the form. (10 points)
A four story building shown below is formed using one level of shoring and two levels of reshoring system. The thickness of each floor or slab is 10in. The slab is designed for its self weight, 30psf superimposed dead load, and 50psf live load. During the construction cycle, a new slab imposes its self weight, 10psf formwork load, and the 50psf of construction load. Use unit weight of concrete as 150pcf. Assume rate of pour as one story per week (5 days) at temperature of 60F. Assume that slab-4 is just poured.
A) Prepare a table to compare the maximum slab load with equal distribution of construction load and slab load capacity when the slab-4 is poured (2.5 points).
B) Identify which slab and under what stage of construction will have the maximum load and calculate the magnitude of that load (2.5 points).
C) Calculate the magnitude of maximum load acting on shores (2.5 points).
D) Also check whether the one level of shoring and two levels of reshoring system work or not (2.5 points).
