27. COLUMNS

Try these first

1. 1.

   What is a column?

   Hint

   Think about its position in a building.

2. 2.

   Name one type of column.

   Hint

   Think about the type that uses ties to restrain steel bars.

3. 3.

   What primary loads do columns resist?

   • Only axial loads
   • Axial and bending loads
   • Lateral loads only

   Hint

   Think about how forces act on a vertical structure.

4. 4.

   True or False: Lateral reinforcement is unimportant for short columns.

   • True
   • False

   Hint

   Consider the role of reinforcement in structural integrity.

5. 5.

   Given a column with a height of 15 ft, width 12 in, depth 8 in, and subjected to a load of 50 kips and a moment of 30 kip-ft, calculate the required reinforcement.

   Hint

   Remember the load factors from your design codes.

6. 6.

   Develop a scenario where a column's eccentric loading might lead to failure. Explain how you would reinforce that column.

   Hint

   Consider both axial and lateral influences.
