Ultimate Strength of Steel Used for Prestressing
Ultimate strength refers to the maximum stress that a material can withstand before it fails. In the case of steel used for prestressing, the ultimate strength is very high.
High Strength Steel
High strength steel is commonly used for prestressing because it can withstand high stresses without breaking. The ultimate strength of the steel used for prestressing is nearly 1500 N/mm2.
Advantages of High Strength Steel
The use of high strength steel in prestressed concrete has several advantages, including:
1. Reduced Dead Load: High strength steel reduces the dead load of the structure, making it lighter and more efficient.
2. Increased Span Length: High strength steel allows for longer spans between supports, reducing the number of supports needed and reducing construction costs.
3. Better Durability: High strength steel has better fatigue and corrosion resistance, increasing the durability of the structure.
Conclusion
In conclusion, the ultimate strength of the steel used for prestressing is nearly 1500 N/mm2. High strength steel has several advantages, including reduced dead load, increased span length, and better durability.
