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...

A column in the upper story of a building is subjected to a compressive load from the following sources: . dead load = 30.8 kips, . occupancy live load = 1.7 kips, (Assume this is from a live load of less than 100 psf, and it is not a garage or place of public assembly.) . roof live load = 18.7 kips, and snow load 19.7 kips. If the load and resistance factor design (LRFD) method is used, what is...
