Auto-calculation of short-term losses for post-tensioned tendons
Model, design, and code-check prestressed beams, deep beams via the more advanced method, CSFM. Compatible stress field method.
Since version 21.1, it is possible to model the prestressing tendons and include them in CSFM analysis. Prestressing losses had to be defined by the user. There is an option of auto-calculation of short-term losses for post-tensioned tendons only. You can use the auto-calculation or still define them, it is up to you. We automatically calculate losses due to friction, anchorage set, and short-term relaxation among short-term losses.
If you wish to calculate short-term losses automatically, just select the option Calculate automatically.
