2.2. Stress-Strain Curve in Tension

Try these first

1. 1.

   What happens to concrete in tension when it reaches its tensile strength?

   Hint

   Think about the point where the material can no longer hold the load.

2. 2.

   Define tensile strength in your own words.

   Hint

   What happens to a rope when you pull too hard?

3. 3.

   What is the tensile strength (ft) of concrete?

   • The maximum compressive force
   • The maximum tensile force
   • The yield point

   Hint

   Focus on tensile, not compressive issues.

4. 4.

   True or False: The stress-strain curve in tension shows ductile behavior in concrete.

   • True
   • False

   Hint

   Think about how concrete behaves when it's pulled.

5. 5.

   Design a simple beam using concrete that must support a tensile load. Analyze how the stress-strain curve influences your material selection.

   Hint

   Consider reinforcing steel or using composite materials.

6. 6.

   Evaluate a scenario where a concrete bridge begins to crack due to excessive tensile stress. Discuss the potential actions an engineer can take.

   Hint

   Look into load management solutions and reinforcement techniques.
