D. EHE Column Design Principles

The EHE 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 end moments, as well as biaxial shear.  Torsional moments are also included if specified in the design brief. Reinforcement is provided by the program based on the forces generated in the Analysis mode and the code clauses outlined below.

The main reinforcing bars may be modified to allow for other bars passing through the section and then re-checked to ensure that the design requirements are satisfied.

All selected load combinations are used to calculate the required reinforcement.  The combination which produces the maximum required reinforcement area is called the "Guiding Load Case", and the bar arrangement is chosen based on that combination.  Detailed printout of the design calculations is also for that combination.
