33.1.2. Behavior of Simple Frames

Try these first

1. 1.

   What is a simple frame?

   Hint

   Think about the elements used in building structures.

2. 2.

   What happens to the maximum moment when using rigid connections?

   Hint

   Consider the meaning of rigidity in connections.

3. 3.

   What is the impact of rigid connections on maximum moments in beams?

   • They increase them
   • They reduce them
   • They have no effect

   Hint

   Think about how rigidity influences moment transfer.

4. 4.

   True or False: Negative moments only occur in rigid structures.

   • True
   • False

   Hint

   Consider the scenarios in which moments are present.

5. 5.

   Design a simple frame with specified vertical loads and calculate the resulting moments and negative moments at the ends, considering the type of connections.

   Hint

   Use moment diagrams to guide your calculations.

6. 6.

   Evaluate how changing beam lengths in a rigid frame affects both maximum and negative moments when subjected to vertical loads.

   Hint

   Consider moment equations and their dependence on length.
