11.2.7. Bottom Column Axial Forces

Try these first

1. 1.

   Define axial force and provide an example.

   Hint

   Think of forces that pull or push in the same line as the member.

2. 2.

   What is the difference between tension and compression?

   Hint

   Consider how a rope responds to being pulled versus how a column responds to being pushed.

3. 3.

   What is the primary function of axial forces in a column?

   • To resist bending
   • To transfer loads
   • To provide thermal resistance

   Hint

   Consider how columns interact within a structure.

4. 4.

   T/F: Axial forces can only be tensile.

   • True
   • False

   Hint

   Think about how they act under different load conditions.

5. 5.

   Design a column that needs to support an axial load of 150 kN, considering safety factors and material properties.

   Hint

   Factor in a safety margin based on the calculated loads.

6. 6.

   Analyze a frame with unequal loading on girders leading to differing axial forces in columns. Describe your approach to equilibrium equations.

   Hint

   Think about how vertical loads shift as you analyze each girder.
