Q: How much yield stress does a twisted bar have more than an ordinary mild steel bar ?
  • A. 50%
  • B. 10%
  • C. 20%
  • D. 30%
Correct Answer: Option A - Twisted bars– • A twisted steel bar is a type of steel reinforcement bar that has been twisted to increase its strength and durability. • Twisted steel bars are commonly used in reinforcement concrete structures such as buildings, bridges, and highways. • Twisted steel bars are also known as prestressing tendons. • These are contained various wires right around 7 wires turned together into a strand. • A twisted bar has considerable increased yield stress about 50% more than the ordinary mild steel bars.
