Select the lightest available W8 section to support the axial loads Pp = 75 k and 125 k if KL = 13 ft and F, = 50 ksi.

Of the types of loads imposed on the Member Load (Beam) are: Concentrated Force, Uniform Force Staad pro True O False The section L75x75x5 SD is double angle iron Staad pro O True False

Select a WT section for the compression member shown in Figure. The load is the total service load, with a live-to-dead load ratio of 2.5:1. Use Fy 5 50 ksi. a. Use LRFD. b. Use ASD 21' 175 k 1

Select the lightest W section for the column shown in the accompanying figure. The loading is 30 kips dead load and 120 kips gravity live load. The member is built into a wall so that it may be considered as continuously braced in the weak direction. Note: Not all of the variable W sections are included in the AISC Manual "Available Strength in Axial Compression" tables. Use (a) A992 steel; (b) Fy = 60 ksi
