Manual Resizing of Members

The resizing of members will be largely controlled by the desired plastic hinge mechanism. To induce the formation of a plastic hinge, it is recommended to resize the member so that the local moment capacity unity ratio is approximately 1.2 at the location of the plastic hinge.

When resizing other members it is important that any plastic hinges formed may redistribute additional moment to that moment. Caution must therefore be taken not to over utilise the section based on the moments before elastic-plastic analysis is carried out.

When the changes are complete conduct a plastic analysis using the Plastic Analysis button

After analysis, review all design briefs in order to determine if the design can be further refined by another phase of resizing, re-analysing, and checking.
