Small coordinates discrepancies between columns and braces that intersect at the same foundation node can cause the program to miss the brace force. This is a rare issue and is most likely due to rounding errors that occur when models are imported from 3rd party programs. In affected models, foundations are designed for loads that do not include the brace forces, which results in an unconservative design.
Fixed in version 15.05.00 and after with an adjustment to tolerances. Alternatively, the problem can be resolved in affected models by deleting and remodeling the braces in RAM Modeler.
