1. About & Disclaimer

    This design software calculates the critical temperature of a Universal Column (Advance ® UKC) exposed to fire. The software also calculates the time to failure when the column is unprotected.

    This software only covers columns in braced frames.

    The design resistance is calculated in accordance with BS EN 1993-1-1 and BS EN 1993-1-2, and the UK National Annex. The user must select the column, the loading and the imposed load category. The user must also select whether the column is at the top storey or an intermediate storey.

    Unprotected columns with a section factor (Am/V) less than 180m-1 are deemed to satisfy a minimum period of fire resistance of 15 minutes, which is the common requirement for open-sided car parks not more than 30m in height.

    Although care has been taken to ensure that the calculated resistances are correct, users should verify the output. The Steel Construction Institute and other parties associated with this software and website assume no responsibilities for errors or misuse of this software, or damage arising from use of this software
