Clause 7.2 of IS:13920-2016 checks the relative strength of beams and columns at a joint to evaluate if any column at a joint is acting as a gravity column or is a part of lateral load resisting system. After the concrete design is completed per IS 13920-2016, then this relative strength check is automatically performed at joints in which all connecting beams and columns were designed. Thus, no new commands are required for this check to be performed so long as all concrete members at a joint are designed. Per Cl 7.2, the sum of all column moment resistances at a joint shall be greater that 1.4× the sum of all beam moment resistances at the same point.

It is recommend that the design of all concrete beams and columns be performed in one concrete block (a "concrete block" is the information contained in the START CONCRETE DESIGN … END CONCRETE DESIGN input section) so this check can be performed. If multiple concrete blocks are defined, all previous relative strength check result will be deleted since multiple design of beams and column designs may change the relative strength of beams and columns at a joint. The strength check performed after the last concrete block will be considered valid and is available as result.
