This design software may be used to verify columns in “simple construction” – subject to axial loads and nominal moments from eccentric beam reactions assumed to be 100 mm from the face of the column. The tool covers Universal Beams (Advance ® UKB) and Universal Columns (Advance ® UKC) in S275 and S355 steel. The verification follows the guidance in SN048bENGB “NCCI: Verification of columns in simple construction – a simplified interaction criterion”. The scope excludes the verification of class 4 sections. The user must select the steel grade, member type, section size and column length. The tool provides the opportunity to input an axial force (from above), and the design values of the reactions on each face of the column at both ends of the column  these reactions are used to calculate the bending moments in the major and minor axis. It is assumed that the stiffness of the adjacent column lengths does not differ from the member to be verified by a ratio greater than 1.5 – so the applied moments are distributed equally between column lengths at the ends of the member.
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
