4.1. Types of Frame Structures

Try these first

1. 1.

   What are the two main categories of frame structures?

   Hint

   Think about the way they resist forces.

2. 2.

   What type of loads do frame structures primarily resist?

   Hint

   Consider what happens during a storm or earthquake.

3. 3.

   What type of frame structure provides better resistance against lateral forces?

   • Rigid Frame
   • Braced Frame
   • Neither

   Hint

   Consider which frame can better withstand wind and earthquakes.

4. 4.

   True or False: Fixed-ended frames allow rotation at the supports.

   • True
   • False

   Hint

   Think about how they connect to the ground.

5. 5.

   Design a simple frame structure with specified loads and calculate the reactions at the supports.

   Hint

   Use Newton's laws of motion to balance forces.

6. 6.

   Analyze a braced frame subjected to lateral forces and determine the effectiveness of the braces.

   Hint

   Consider the triangle formed by diagonal members.
