Q: Generally, modulus of elasticity of steel used for design of Prestress concrete structures compared to design of RC structure is:
  • A. More
  • B. Less
  • C. Same
  • D. None of these
Correct Answer: Option A - Generally, modulus of elasticity of steel used for design of prestress concrete structures compared to design of RC structure is more. • For prestressed structural elements, high strength concrete is used primarily because high modulus of elasticity and creep values are lower.
A. Generally, modulus of elasticity of steel used for design of prestress concrete structures compared to design of RC structure is more. • For prestressed structural elements, high strength concrete is used primarily because high modulus of elasticity and creep values are lower.
