6. Design Codes

The design code module allows concreteproperties to be easily used in the context of common reinforced concrete design standards. concreteproperties currently supports the following design codes:

• 6.1. AS 3600:2018
• 6.2. NZS3101:2006

Warning

The current implementation of moment interaction diagrams in concreteproperties allows the user to define the angle the neutral axis makes with the horizontal. Asymmetric sections with a non-zero neutral axis angle will result in biaxial bending moments. When generating moment interaction diagrams using this approach, the ratio between the bending moments m_x and m_y will change depending on the level of axial load. As a result, without generating biaxial bending diagrams, a false impression of demand/capacity may be generated when operating close to the design curve. A future version of concreteproperties will incorporate a constant ‘load-angle’ approach, which will keep the ratio of m_x to m_y constant for a given moment interaction diagram, rather than keeping the neutral axis angle constant. Further discussion of this issue can be found here.
