Steel Framing

A steel frame consists of a skeleton frame structure comprising of horizontal I-beams and vertical steel columns fitted in a rectangular grid building construction to brace the floors, walls, and the roof of the building held onto the frame. Due to the implementation of this methodology, the construction of the skyscrapers was feasible.

Question

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.
