1.4.3. Columns

Try these first

1. 1.

   What is the primary function of a column in a structure?

   Hint

   Think about what a column does in a building.

2. 2.

   What happens to a column when it buckles?

   Hint

   Consider the stability of objects when overloaded.

3. 3.

   What is the primary load resisted by columns?

   • Bending loads
   • Shear loads
   • Axial loads

   Hint

   Think about the direction of forces on a vertical structure.

4. 4.

   True or False: Columns can only fail due to bending.

   • True
   • False

   Hint

   Consider how other forces might affect stability.

5. 5.

   A column is subjected to a critical load of 500 kN. If the buckling material is known to have a yield strength of 240 MPa, determine the minimum cross-sectional area required to prevent buckling.

   Hint

   Remember the formula A = P / σ.

6. 6.

   In a design scenario, a beam-column in a multi-story building is subjected to both axial and lateral loads. Explain how you would approach verifying the stability of this structure.

   Hint

   Consider both loads and think through the design and analysis process.
