A partially prestressed member is one in which-a)No tensile stresses ...
Partial Prestressing When the level of prestressing is such that under tensile stresses due to service loads, the crack width is within the allowable limit, it is called Partial Prestressing.

A partially prestressed member is one in which-a)No tensile stresses ...
A partially prestressed member is a structural element that is reinforced with both prestressing steel and mild steel. It is designed to withstand both tensile stresses and cracking under service loads.
Tensile Stresses Permitted:
In a partially prestressed member, tensile stresses are allowed to develop under service loads. This is because not all the loads on the member are carried by the prestressing steel. The mild steel reinforcement helps to carry a portion of the load, allowing the prestressing steel to work more efficiently.
Cracking Permitted:
Under service loads, some amount of cracking is allowed in a partially prestressed member. This cracking occurs due to the presence of tensile stresses in the member. However, the cracking is controlled and limited to acceptable levels through the use of mild steel reinforcement.
Advantages of Partially Prestressed Members:
1. Increased Load-Carrying Capacity: The combination of prestressing steel and mild steel reinforcement allows partially prestressed members to carry higher loads compared to reinforced concrete members.
2. Improved Crack Control: The presence of both prestressing steel and mild steel reinforcement helps to control and limit cracking in the member. This improves the durability and aesthetics of the structure.
3. Reduces Deflection: Partial prestressing reduces the deflection of the member under service loads. This is important for structures that require minimal movement or have strict deflection criteria.
4. Cost-Effective: Partially prestressed members offer a cost-effective solution as they require less prestressing steel compared to fully prestressed members. The use of mild steel reinforcement also helps to reduce costs.
Conclusion:
In conclusion, a partially prestressed member is designed to withstand both tensile stresses and cracking under service loads. It combines the advantages of prestressing steel and mild steel reinforcement to enhance the load-carrying capacity, crack control, and deflection behavior of the member.
