3.4. Factors Influencing Creep

Try these first

1. 1.

   Define creep in your own words.

   Hint

   Think about how materials behave under stress.

2. 2.

   What effect does higher humidity have on creep?

   Hint

   Consider how moisture affects materials.

3. 3.

   What happens to creep as stress levels increase?

   • It decreases
   • It remains constant
   • It increases

   Hint

   Think about the mechanical properties of materials.

4. 4.

   True or False: Lower humidity levels result in lower creep.

   • True
   • False

   Hint

   Consider how moisture affects concrete.

5. 5.

   A structural engineer needs to ensure a reinforced concrete bridge will not exceed creep limits. Given varying humidity and temperature conditions, devise a monitoring plan for these elements.

   Hint

   Think of continuous assessments.

6. 6.

   You are designing a concrete mix for a new commercial building. Describe your choice of materials and how you would balance them to mitigate creep.

   Hint

   Consider material interactions.
