Problem 1:
Given: In a given floor system, a 5-in concrete slab supported by T-beams of 24-ft spans, supporting 354 psf
live load. The T-beams are spaced 2x4 ft on center, and bw (width of the beam web) = 15 inches. Total T-beam
height is 25 inches. f'c = 4,000psi, fy = 60,000psi.
Design the T-beam. Show all steps. Sketch your Design.
Problem 2:
Given: A 25"x25" column is subject to a
factored axial load of Pu=1,200 kips, and
factored design moment of Mu-354 kips-ft.
f'c 4,000psi, fy = 60,000psi.

Then a point such as E was marked on the ground on the line between A and B and at a horizontal distance from A equal to 50.00 ft. Finally, with the transit set up over the point E, the difference in elevation between the point A and the transverse axis F of the transit at E was found to be 3.47 ft, and the vertical angle d between the horizontal line through F and the line of sight to the point B was +18º 07'.
