27.2. Short Columns

Try these first

1. 1.

   What is a short column?

   Hint

   Think about its dimensions relative to normal columns.

2. 2.

   What happens when the load is applied eccentrically?

   Hint

   Recall the difference between axial and bending loads.

3. 3.

   What is a characteristic of short columns?

   • They can only resist axial loads.
   • They can resist combined axial and bending loads.
   • They are not important in structural design.

   Hint

   Think about their design purpose.

4. 4.

   True or False: Eccentric loads do not affect the behavior of short columns.

   • True
   • False

   Hint

   Consider how load placement can change results.

5. 5.

   Calculate the maximum load a short column with dimensions 20 inch height and 12 inch width can bear if the materials have the following properties: f_c = 4000 psi and f_s = 60000 psi.

   Hint

   Remember to assess both the concrete and steel's bearing capacities.

6. 6.

   Explain the design considerations for a short column under eccentric loading. Discuss reinforcement strategies to prevent both yielding and crushing failures.

   Hint

   Include specific measures for maintaining steel and concrete support across all stress planes.
