Tendon #a has a radius (b) that is less than the minimum allowable (c).
Parabolic tendons with a large drape relative to their length have a small radius. A warning is triggered when the tendon segment radius is less than the minimum radius for that tendon system.
A tendon’s minimum (vertical) radius is specified in the Materials section. RAM Concept does not check horizontal radii as tendon segments are straight in plan.
The radii shown are suggestions based on industry standards. You can change them based on advice from prestress companies.
Note: The warning can be indicative of an
overbalanced condition (too much uplift) for parabolic tendons.
To remove
the warning, you can adjust the tendon profile or change the minimum radius in the
Material section. To edit the minimum radius
