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.

Bending is about the x-axis of each member in the unbraced frame. Determine the value for G (that would be used for GA or GB in the alignment charts) at point G in the frame. Girders BF, CG and DH are W21 x 44 and have a length of L1 = 22 ft.Girders FJ, GK and HL are W24 x 55 and have a length of L2 = 34 ft.Columns AB, EF and IJ are W10 x 68 and have a length of L3 = 14 ft.Columns BC, FG and JK are W10 x 45 and have a length of L4 = 10 ft.Columns CD, GH and KL are W10 x 33 and have a length of L4 = 10 ft.

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 = 27 ft, L2 = 9 ft, and L3 = 18 ft.

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.

If a compression member is supported differently with respect to each of its principal axes, the effective length will be the same for both directions.

A column is fabricated by bolting a 5/8 x 6 plate to the bottom of a W14x342. Determine the distance from the bottom of the plate to the centroid of the composite cross section.

A column is fabricated by welding a 5/8 x 18 plate to the left and right of a W14x61. Determine the moment of inertia about the y axis.
