A W14x43 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Can it support a dead load of 150 kips and a live load of 170 kips? Use ASD. Let L1 = 30.8 ft, L2 = 14.8 ft, and L3 = 16.0 ft.

A column is fabricated by welding a 5/8 x 18 plate to the left and right of a W14x99. 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.

Can an A992 steel WT18 x 75 column with an effective length of 20 feet in both directions support a dead load of 50 kips and a live load of 40 kips? Use ASD.

A W12 x 50 column is made from ASTM A572 Gr. 60 steel and has a length of 35 ft with Kx = 2.4 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W14x61 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Can it support a dead load of 180 kips and a live load of 180 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

A column is fabricated by bolting a 1 x 6 plate to the bottom of a W14x48. Determine the distance from the bottom of the plate to the centroid of the composite cross section.

A W14x159 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 = 21 ft, L2 = 8 ft, and L3 = 13 ft.

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 WT15 x 62 column with an effective length of 16 feet in both directions support a dead load of 100 kips and a live load of 120 kips? Use LRFD.
