Introduction to pre-stressed concrete structures: Concepts of Prestressing- Historical development of prestressing-Design Codes for PreStressed Structures- Advantages & Limitations of Pre-stressed Concrete Material – Need for High Strength Concrete- High Tension Steel- Types of Prestressing Steel.

Losses of Prestressing and Prestressing Systems: Losses- Immediate losses due to Friction and wobble, Elastic shortening Anchorage Slip Time dependent losses due to Creep, Shrinkage and Relaxation losses – Introduction to Pre-stressing systems Pre -Tensioning Mechanical pre-stressing Devices Post -Tensioning Devices Anchorage Devices Chemical Pre-stressing – Electrical Pre-stressing

Principle and Methods of design: Combined Load Approach – Internal Couple Approach Load Balancing Approach Steel Stress in Bonded and Un-bonded tendons – Flexure and Shear Crack and Deflection – Design as per IS 1343 – Design of Anchorage zone End block- Cable Profiling for different beams Mechanism of Transfer of Prestress in Pre-Tensioning System and Post Tensioned system

Applications of Pre-stressing: Circular Prestressing Prestressed Concrete Pipes Pre-stressing in Buildings Introduction Types and Design of Beams One-way Slabs Two-way Slabs – Flat slabs Structures – Tanks, Poles & Piles – Partial Prestress – behavior, advantages and disadvantages Remember the concepts of Prestressing
