Select the lightest HP16 column with an effective length of 15 feet that can support a dead load of 270 kips and a live load of 810 kips. Assume Fy = 50 ksi. Use ASD.

Select the lightest HP16 column with an effective length of 15 feet that can support a dead load of 220 kips and a live load of 660 kips. Assume Fy = 50 ksi. Use LRFD.

A W14 x 90 column is made from ASTM A36 steel and has a length of 15 ft. The column is only supported at its ends. Both ends are fixed. Determine the design strength, φcPn, for this column. Assume the shape is nonslender.

A W18 x 35 column is made from ASTM A36 steel and has a length of 26 ft. The column is only supported at its ends. One end is fixed and the other is pinned. Determine the critical stress, Fcr, for this column, which is also called nominal stress, Fn, in AISC 360-22.

A W8 x 67 column is made from ASTM A572 Gr. 42 steel and has a length of 26 ft. The column is only supported at its ends. Both ends are fixed. Determine the nominal compressive strength, Pn, for this column. Assume the shape is nonslender.

A W18 x 35 column is made from ASTM A36 steel and has a length of 20 ft. The column is only supported at its ends. Both ends are fixed. Determine the allowable strength, Pn/Ωc, for this column. Assume the shape is nonslender.

Can a W14 x 53 column with an effective length of 7 feet support a dead load of 120 kips and a live load of 100 kips? Use LRFD.

A W10 x 77 column is made from ASTM A36 steel and has a length of 34 ft. The column is only supported at its ends. One end is fixed and the other is pinned. Determine the elastic buckling stress, Fe, for this column.

A W14 x 90 column is made from ASTM A572 Gr. 42 steel and has a length of 31 ft. The column is only supported at its ends. Both ends are fixed. Determine the allowable strength, Pn/Ωc, for this column. Assume the shape is nonslender.

Using the column load tables, select the lightest W14-shape with an effective length of 15 ft that will support an LRFD design load of 500 kips.
