Select the lightest W section to serve as an axially loaded column 28 ft long, in a braced frame, with additional lateral support in the weak direction at mid-height. The load to be carried is 65 kips dead load and 150 kips live load. Assume the top and bottom of the column are hinged.

a) Use A992 and indicate first and second choices

b) Use A572 Grade 60, indicating first and second choices

Using LRFD, select a 30-ft-long W section of A992 steel with a nominal depth of 10 in (a W12) to support a tensile service dead load PD=130kand a tensile service live load PL=110k. In addition, the section is to comply with the slenderness ratio limit from AISC D1 to prevent sag of the member. As shown in the figure below, the member is to have two lines of bolts in each flange for 7/8-in bolts (at least three in a...

Select the lightest W10 section. Using Fy=50ksi and Fu= 65ksi to select trial sizes and check for Gross Section Yielding and Tensile Rupture. Assume the member is to have two lines of bolts in each flange. (use ASD method) Pd - dead load = 225 ksi Pl - live load = 150 ksi L - member length = 28 ft Bolt diameter = 7/8 in Select the lightest W12 not W10.

Select the lightest W14 section to carry an axial compression of P = 100 kips dead load, and 140 kips live load; along with a strong axis bending moment of 125 kip-ft dead load and 325 kip-ft live load. Assume the moment acts along the entire 15 foot length of the member, and the ends are pin-pin connections.
