A column is fabricated by bolting a 5/8 x 6 plate to the top and bottom of a W14x68. Determine the moment of inertia about the y axis.

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 W18 x 55 and have a length of L1 = 24 ft.Girders FJ, GK and HL are W24 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 = 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 W18 x 35 column is made from ASTM A572 Gr. 42 steel and has a length of 16 ft with Kx = 2.4 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

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.

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 = 24 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 54 and have a length of L3 = 14 ft.Columns BC, FG and JK are W10 x 39 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 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.
