1.5.4. Surface Structures

Try these first

1. 1.

   What is a surface structure?

   Hint

   Think about how materials are shaped in structures.

2. 2.

   Name one material commonly used in surface structures.

   Hint

   Consider what materials can become thin but strong.

3. 3.

   What is the primary way surface structures support loads?

   • Through bending
   • Through tension and compression
   • Through shear forces

   Hint

   Consider how a stretched rubber band works.

4. 4.

   True or False: Surface structures are thick and heavy.

   • True
   • False

   Hint

   What do we mean by thin materials in structural engineering?

5. 5.

   Design a simple surface structure (a canopy) to protect a small area from rain. List material choices and justify their use regarding tension and compression.

   Hint

   Think about the shapes that can best channel rain away.

6. 6.

   A shell structure is experiencing dynamic loads due to wind. Describe how the design must adapt to handle these loads effectively.

   Hint

   Consider how airplane wings are designed for wind resistance.
