Friction, Elongation and Long-Term Stress Loss Calculation Software for
ADAPT-FELT is the industry standard program for the calculation of elongations, friction loss, and long-term stress loss in prestressing tendons. It covers both bonded and unbonded tendons with regular or irregular geometries in two or three dimensions. In addition to a detailed tabular report, the program displays the geometry of tendon and the distribution of stress along the tendon.
FELT is a computer program for the Friction, Elongation and Long-Term stress loss computation of tendons in prestressed structures. For a given tendon geometry and stressing specification, the software computes the stresses along the tendon length. Tendon geometry can be selected from the program's pre-defined profiles, or, in the case of irregular tendons, the geometry can be input through tendon coordinates. The immediate loss computation includes the friction and seating of tendon (wedge draw-in). The long-term losses include creep, shrinkage and relaxation in steel. The computations are based on the recommendations of ACI Committee 423.
