Question 1.
What is a plastic hinge?
Show hintHide hint
Think about where yielding occurs in a beam.
Question 2.
List the three classifications of steel beam sections.
Show hintHide hint
Remember the types of buckling behavior.
3Question 3.
What happens at a plastic hinge?
- The beam breaks
- The beam rotates without a moment increase
- The beam supports more load
Show hintHide hint
Focus on the behavior of material at its yield point.
4Question 4.
True or False: A compact section can buckle under maximum load.
- True
- False
Show hintHide hint
Consider the definition and capabilities of a compact beam.
Question 5.
Design a single-span beam that supports a specified load. Classify the section and justify that classification.
Show hintHide hint
Don’t forget to evaluate the width-to-thickness ratio!
Question 6.
Analyze a fail scenario where a beam experiences plastic hinge formation and local buckling. Suggest design modifications to improve performance.
Show hintHide hint
Consider overloading and geometric properties of the sections analyzed.
