HW ASSIGNMENT $6$: STEEL COLUMN DESIGN

Directions: Read each problem statement and elaborate your answer for the question posed.

References: Lecture $14$

PROBLEM $1$:

Design the two$-$story column shown below. The column is braced in the weak direction at the first$-$floor level and un$-$braced in the strong direction for the full height. Load at the roof is $60$ kips $.$ Consider that the column is pinned at the ends. Determine the most economical wide flange section. Architectural requirement limits the column selection to $8-$inch width columns. Use steel Grade $50.$

Roof beam

PROBLEM $2$:

For the wall shown below:

A$.$ W$828$ columns are used as main members with bracing of the weak axis, as shown. What is the safe axial load capacity of the column $($ P $)?$

B$.$ Determine the safe axial load if the bracing is omitted. Again, use steel Grade $50$
