As of the 2017.g version, CYPECAD allows users to analyse the project even if beams (that are not foundation beams, strap beams, supports or walls) have been introduced at the base of columns that have been defined as having external fixity. The program emits a message warning users of this situation, which allows them to ensure the introduction has been carried out intentionally and is not an error.
By introducing these beams at the base of columns with external fixity, users can introduce raised floor slabs containing beams that transmit loads to the columns.
