Is a W-shape with the following details considered slender according to AISC 360 Table B4.1a?bf/2tf = 12h/tw = 26Fy = 54 ksi

Can a W14 x 53 column with an effective length of 6 feet support a dead load of 100 kips and a live load of 140 kips? Use LRFD.

The ratios bf/2tf and h/tw are called _______ and denoted by the Greek letter ___.

A W12x35 beam made from A992 steel would be classified as _______.

Many of the shapes commonly used for columns are not slender, and the reduction factor Q will not be needed.

A W12 x 50 column is made from ASTM A572 Gr. 42 steel and has a length of 19 ft. Both ends are fixed against rotation and translation. Determine the effective slenderness ratio.

A W14 x 90 column is made from ASTM A572 Gr. 60 steel and has a length of 20 ft. The column is only supported at its ends. Both ends are fixed. Determine the elastic buckling stress, Fe, for this column.

Determine the effective length of the following column where L = 16 ft.

What is L/r?

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 450 kips.
