A column is fabricated by welding a 1 x 18 plate to the left and right of a W14x53. Determine the moment of inertia about the y axis.

A W14x90 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 = 11 ft, and L3 = 19 ft.

A column will buckle in the direction corresponding to the smallest slenderness ratio.

A column is fabricated by welding a 3/8 x 18 plate to the left and right of a W14x132. Determine the moment of inertia about the y axis.

A W18 x 35 column is made from ASTM A572 Gr. 60 steel and has a length of 40 ft with Kx = 1.8 and Ky = 1.0. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W16 x 50 column is made from ASTM A36 steel and has a length of 30 ft with Kx = 1.8 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 W18 x 46 and have a length of L1 = 26 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 77 and have a length of L3 = 16 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 33 and have a length of L4 = 12 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 240 kips and a live load of 160 kips? Use LRFD. Let L1 = 24.4 ft, L2 = 8.4 ft, and L3 = 16.0 ft.

A column is fabricated by welding a 1/2 x 18 plate to the left and right of a W14x120. Determine the moment of inertia about the y axis.

A column is fabricated by welding a 1/4 x 18 plate to the left and right of a W14x193. Determine the moment of inertia about the x axis.
