Notes:Anchorage spacings are in accordance with test requirement of AASHTO (The Special Anchorage Device Acceptance Test Procedure, AASHTO 2000).For proper design and detailing of anchorage zones and related reinforcement, refer to the VSL Publication Detailing for Post-Tensioning.

Dimensions are valid for: fci (psi) is the nominal minimum concrete cylinder strength at the time of stressing. Maximum prestressing force may be applied when concrete reaches a cylinder

strength of 3,500 psi (24 MPa) and 5,500 psi (38 MPa) respectively. Temporary overstressing to 80% of Guaranteed Ultimate Tensile Strength. Yield strength of spiral reinforcement: Grade 60 (400 MPa). Tie one and one-half turns of spiral at both ends. Additional orthogonal reinforcement may be required in the local anchorage zone as

determined by design. Spirals may be replaced by suitable orthogonal reinforcement. Information for other concrete strengths and conditions is available from your local

VSL Representative. Spiral reinforcement shall be centered on the anchorage assembly and be placed

directly behind the bearing plate as indicated above.
