Can an A992 steel WT15 x 62 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.

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 = 24 ft.Girders FJ, GK and HL are W21 x 50 and have a length of L2 = 34 ft.Columns AB, EF and IJ are W10 x 77 and have a length of L3 = 14 ft.Columns BC, FG and JK are W10 x 45 and have a length of L4 = 12 ft.Columns CD, GH and KL are W10 x 26 and have a length of L4 = 12 ft.

A W14x74 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 = 28 ft, L2 = 8 ft, and L3 = 20 ft.

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 140 kips and a live load of 220 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

Use the Jackson-Mooreland Alignment Charts and the values for G shown below to determine the value of K for a member in a moment frame.GA = 4GB = 6

A column is fabricated by bolting a 3/4 x 6 plate to the bottom of a W14x159. Determine the distance from the bottom of the plate to the centroid of the composite cross section.

Bending is about the x-axis of each member. Determine the value for G (that would be used for GA or GB in the alignment charts) at point F in the frame.Girders BF, CG and DH are W18 x 55 and have a length of L1 = 26 ft.Girders FJ, GK and HL are W24 x 68 and have a length of L2 = 28 ft.Columns AB, EF and IJ are W10 x 88 and have a length of L3 = 16 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 26 and have a length of L4 = 10 ft.

A W8 x 67 column is made from ASTM A36 steel and has a length of 21 ft with Kx = 2.1 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

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.

Whenever possible, the designer should provide extra support for the _______ of a column. Otherwise, the member is inefficient and has an excess of strength in one direction.
