The total weight of 6"-thick entire slab. c. Determine the following for Beam B2 i. What are the beam width, depth, and length dimensions? ii. What is the beam tributary width? ii. What is the total beam weight? (note: do not include the slab at top of the beam) iv. What is the beam average weight (in pounds per sq ft)?

A prestressed concrete has a rectangular section with the following data: b = 400 mm, h = 800 mm, L = 12 m, f. = 69 MPa, fp = 1,860 MPa. f = 1,600 MPa, f. = 1,012 MPa, f = f = 415 MPa, Aps = 690 mm², A, = 1,290 mm², A, = 400 mm², d₂ = d₂ = 725 mm, d'= 75 mm. Determine the nominal moment resistance (kN-m). Make assumptions when necessary.

What is the minimum area (Asmin) for the following concrete beam: b = 10 in, d = 17 in, fy = 60000 psi, and f'c = 5000 psiNote: This is an ACI code check and not required As determined by the moment. Answer in inches^2 and to 3 decimal places. Type your answer...
