The program issues bold warnings in advance of the table of three circumstances:
If design fails because the program detects and irregularity and illegal seismic design parameters for that irregularity
There are concerns regarding forces used to design hold-downs and drag struts to comply with NBC 4.1.8.15-2.
If the program detects design parameters such that the user must check for an irregularity that the program cannot detect.
Following shear wall design , one of a total of 7 possible explanatory warning messages can be sent to the screen
Post-Disaster and Types 1 or 7
Post disaster and Type 3, 4, or 5
Type 3, 4, 5 - And there is a weak storey, indicating that the drag strut and hold-down forces are calculated using the lower storey capacity when they should be using the higher upper storey capacity to comply with NBC 4.1.8.15-2.
Type 3, 4, 5 - No weak storey but program uses shear wall capacity in place of design shear for hold-down calculations
Type 6, and seismic design not permitted unless design forces factored by RoRd
