A column is fabricated by bolting a 3/8 x 6 plate to the top of a W14x74. Determine the distance from the bottom of the W-shape to the centroid of the composite cross section.

A column is fabricated by welding a 1/4 x 18 plate to the left and right of a W14x68. Determine the moment of inertia about the y axis.

A column is fabricated by welding a 3/4 x 18 plate to the left and right of a W14x176. Determine the moment of inertia about the x axis.

Can an A992 steel WT7 x 41 column with an effective length of 16 feet in both directions support a dead load of 120 kips and a live load of 60 kips? Use LRFD.

A column will buckle in the direction corresponding to the largest slenderness ratio, and that ratio would be used in the determination of the column’s compressive strength.

A column is fabricated by welding a 3/4 x 18 plate to the left and right of a W14x90. Determine the moment of inertia about the x axis.

Can an A992 steel WT7 x 41 column with an effective length of 20 feet in both directions support a dead load of 60 kips and a live load of 70 kips? Use ASD.

A W8 x 67 column is made from ASTM A572 Gr. 42 steel and has a length of 26 ft with Kx = 1.7 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W14x176 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Determine the value of the controlling slenderness ratio Lc/r. Let L1 = 23 ft, L2 = 8 ft, and L3 = 15 ft.

A column is fabricated by bolting a 3/8 x 6 plate to the top of a W14x53. Determine the distance from the bottom of the W-shape to the centroid of the composite cross section.
