Product Overview
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. It is applicable to commercial and
residential buildings, ground supported slabs,
bridge structures, foundations and piles.
For buildings, frames, bridges and special
structures.

Product Details
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. The software handles both
bonded and unbonded systems. As an option, for
shop drawings, friction and elongation
calculations can be performed without long-term
stress losses. The software comes with thorough
documentation, extensive examples and a section on
verification. It is an effective analysis/design
tool for both consulting engineers and
prestressing suppliers. |
