A W1422 acts compositely with a 4-inch-thick floor slab whose effective width b is 90 inches. The beams are spaced at 7 feet 6 inches, and the span length is 30 feet. The superimposed loads are as follows: construction load = 20 psf, partition load = 10 psf, weight of ceiling and light fixtures = 5 psf, and live load = 60 psf, A992 steel is used, and fc=4 ksi. Determine whether the flexural strength is adequate. a. Use LRFD. b. Use ASD.
A steel pile (H-section; HP 310 125; see Table 12.1a) is driven into a layer of sandstone. The length of the pile is 25 m. Following are the properties of the sandstone: unconfined compression strength = qu(lab) = 80 MN/m2 and angle of friction = 36. Using a factor of safety of 3, estimate the allowable point load that can be carried by the pile. Use [qu(design) = qu(lab)/5].
A steel pile (H-section; HP 360 1.491; see Table 18.1) is driven into a layer of sandstone The length of the pile is 18.9 m. Following are the properties of the sandstone: Unconfined compression strength = qu(lab) = 78.7 MN/m2 Angle of friction = 36 Using a factor of safety of 3, estimate the allowable point load that can be carried by the pile. Use Eq. (18.42).
Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?
Prepare a typical bay estimate based on the following information: a. Bay size of 350 feet and a building perimeter of 1,100 feet. b. There are 50 bays in the building. c. Unit prices: • Concrete piles: $950.00 each • Concrete pile caps: $725.00 each • Slab-on-grade: $12.50 per sq. ft. • Structural steel frame: $4.90 per sq. ft. • Roof structure: $10.75 per sq. ft. • Roofing: $8.20 per sq. ft. • Plumbing & HVAC: $9.80 per sq. ft. • Electrical: $6.10 per sq. ft. • Exterior foundations: $100.00 per linear ft. • Exterior walls: 728.00 per linear ft.
A driven closed-ended pile, circular in cross section, is shown in Figure P12.7. Calculate the following. The ultimate point load using Meyerhof’s procedure. The ultimate point load using Vesic’s procedure. Take Irr = 50. An approximate ultimate point load on the basis of parts (a) and (b). The ultimate frictional resistance Qs. [Use Eqs. (12.42) through (12.44), and take K = 1.4 and δ′ = 0.6ϕ′.] The allowable load of the pile (use FS = 4).
