See lessWhat is the significance of relaxation losses in prestressed concrete?
Relaxation losses refer to the gradual decrease in prestressing force over time due to the relaxation of steel tendons, affecting long-term performance and serviceability of prestressed structures.

Factors include project requirements, construction constraints, durability considerations, maintenance needs, and life-cycle cost analysis.
See lessWhat is the purpose of unbonded tendons in prestressed concrete?
Unbonded tendons are encased in plastic or steel ducts and not bonded to the surrounding concrete, allowing for easier replacement or adjustment of prestressing force and reducing the risk of corrosion.
