D. ECCS 203 Column Design Principles

The ECCS 203 Column Design Brief is for prismatic, rectangular solid or circular shaped members.  Members may be built up from multiple elements, but only the member end moments are considered, so only single height columns are recommended.

Design Principles

Columns are designed for axial force and biaxial bending at the ends. All active loadings are tested to calculate reinforcement. The loading which produces maximum reinforcement is called the critical load and is displayed. The requirements of ECCS203-2004 equation 6-37,6-38,6-41 etc are followed, with the user having control on the effective length parameters. Bracing conditions are controlled by using the BRACE parameter. The program will then decide whether or not the column is short or slender and whether it requires additional moment calculations.
