Design a square tied column to carry axial service loads of 320
kips dead load and 190 kips live load. There is no identified
applied moment. Assume that the column is short. Use f’c =4000 psi
and fy = 60,000 psi. Also, draw the flexural and shear
reinforcement on a sketch.

A (9’x9’x32”) square footing is supporting 230 kips dead load
and 130 kips live load from 18-in square column. The allowable
bearing soil pressure is 5000 psf. There is no over-burden soil
weight. Check if the footing area satisfies the soil bearing
pressure requirements. Also, check if the thickness satisfies the
shear ( two and one way) requirements. Finally, design the flexural
steels each direction.

Problem 2. Design and select an ASTM A992 (Fy" 50 ksi) W-shape column to carry an axial dead load of 140 kips and live lond of 420 kips. The column is 30 feet long, and is pinned top and bottom in both axes. In addition, the column is laterally braced about the y-y axis (local weak/minor axis of the section) and torsionally braced at the midpoint. Limit the column size to a nominal 14 in. shape, that is W14 shape...

Problem 5: Design of Idealized Compression Member A 20-ft long column is pinned at the bottom and fixed against rotation, but free to translate, at the top. It must support a service dead load of 110 kips and a service live load of 110 kips. a) Select the lightest W12 of A992 steel. Use the column load tables b) Select the lightest W18 of A992 steel. Use the trial-and-error process.
