||**** INFO_STPHDR – Plastic hinge displacement results do not exist. Command ignored.
**** INFO_STPHDR – Output of plastic hinge ductility factors first requires a push-over analysis. Command ignored.
☞ Explanation: These two informational messages are printed if a pushover analysis has not been executed prior to giving the LIST PLASTIC HINGE DUCTILITY RATIO command. The LIST command is merely ignored and the condition can be corrected by executing the pushover analysis with the PERFORM PUSHOVER ANALYSIS command.
