1.5. Measurement of Creep

Try these first

1. 1.

   What is the primary tool used to apply load during a creep test?

   Hint

   Think about the equipment that holds the concrete sample.

2. 2.

   What does the Creep Coefficient indicate?

   Hint

   Consider what happens over time under constant stress.

3. 3.

   What does the Creep Coefficient represent?

   • The ratio of compressive strength
   • The ratio of creep strain to elastic strain
   • The total deformation in concrete

   Hint

   Focus on the definitions we've discussed in class.

4. 4.

   Is the presence of companion specimens essential for accurate creep measurement?

   • True
   • False

   Hint

   Remember how we discussed isolating different factors in creep tests.

5. 5.

   Given a Creep Coefficient of φ = 2 for a structure, calculate the total creep strain if the elastic strain at loading was measured as 500µε.

   Hint

   Focus on understanding the relationship expressed by the Creep Coefficient.

6. 6.

   A creep frame setup has an applied constant load. Discuss how environmental factors such as humidity might influence the creep results. Include at least two environmental factors in your discussion.

   Hint

   Consider how moisture content changes can impact material properties.
