For the frame shown below, use the following information: • Columns are oriented so that the y axis is in plane and the x axis is out of plane. • All columns and girders are A992 steel. • The girders to column connections in the plane of the elevation are as indicated. • All out of plane girder to column connections are simple. • Base plate fixity as indicated applies to x and y axis. 1. Determine the ultimate load Pu for column 2 (i.e. along grid line 2) Pu= 2. Determine the nominal axial capacity, ¢P, for column 2 according to part 16, specifications of AISC steel manual 3. Determine the nominal axial capacity, oPn using the design tables. PPn= 4. Check if column 2 is safe or not Show all calculations and identify each step for credit.
