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 140 kips and a live load of 240 kips? Use LRFD. Let L1 = 30.8 ft, L2 = 14.8 ft, and L3 = 16.0 ft.

If a support is pinned, the value of G should be taken as _____.

A column will buckle in the direction corresponding to the largest _______ ratio.

A W14x74 made with A992 steel is pinned at both ends and braced in the weak direction as shown. Can it support a dead load of 240 kips and a live load of 240 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

A W10 x 77 column is made from ASTM A572 Gr. 42 steel and has a length of 17 ft with Kx = 2.2 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

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 W14x233 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 = 30 ft, L2 = 10 ft, and L3 = 20 ft.

Determine the effective length factor, Kx, for column FG of the frame, assuming that the frame is sidesway inhibited and that all of the assumptions on which the alignment charts were developed are met.Girders BF, CG and DH are W18 x 35 and have a length of L1 = 20 ft.Girders FJ, GK and HL are W21 x 55 and have a length of L2 = 36 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.

Can an A992 steel WT12 x 31 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.

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