A W16 x 50 column is made from ASTM A572 Gr. 42 steel and has a length of 30 ft with Kx = 1.9 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. 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 46 and have a length of L1 = 20 ft.Girders FJ, GK and HL are W21 x 50 and have a length of L2 = 30 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 39 and have a length of L4 = 10 ft.Columns CD, GH and KL are W10 x 30 and have a length of L4 = 10 ft.

A W10 x 77 column is made from ASTM A36 steel and has a length of 25 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 top of a W14x120. Determine the distance from the bottom of the W-shape to the centroid of the composite cross section.

A W14x176 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 = 23 ft, L2 = 8 ft, and L3 = 15 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 = 20GB = 6

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

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 W21 x 44 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 88 and have a length of L3 = 16 ft.Columns BC, FG and JK are W10 x 49 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 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 150 kips and a live load of 170 kips? Use ASD. Let L1 = 30.8 ft, L2 = 14.8 ft, and L3 = 16.0 ft.

A column is fabricated by welding a 5/8 x 18 plate to the left and right of a W14x99. Determine the moment of inertia about the x axis.
