22.3. Examples

Try these first

1. 1.

   What is a beam column?

   Hint

   Think about what role it plays in a structure.

2. 2.

   What material is used in the provided example?

   Hint

   Recall from the section what materials are specified.

3. 3.

   Which material is used in the example calculations?

   • A992
   • A36
   • S235

   Hint

   Consider the section’s mention of material properties.

4. 4.

   True or False: Moment magnification decreases the moment acting on a beam.

   • True
   • False

   Hint

   Think about what happens to beams under lateral forces.

5. 5.

   A beam column with a yield strength of 50 ksi is subjected to an applied moment of 100 k-ft. Calculate whether the beam is adequate if its section modulus is 200 in^3.

   Hint

   Always verify your moment capacities against the applied loads!

6. 6.

   Analyze a situation where a beam column has to support increased lateral loads. Discuss how this affects its design and what calculations need to be adapted.

   Hint

   Consider the lateral-torsional buckling criteria!
