Why does the code compliance report show an SIF = 1 for the Sustained Case and 1.3 for all other cases?
See tools/Model Options/ Results/Set Sustained SIF to 1. This field is only active for the B31.1-1967, B31.3, B31.4, B31.8, DNV, SNCT, CAN-Z662, and KHK level1 codes (it is closed for all others). These codes define stress intensification factors (SIF’s) for the expansion stress category only. This option has been provided since no guidelines are presented for the sustained and occasional stress categories. If disabled, AutoPIPE will apply the expansion category SIF’s to all other stress categories. When it is enabled, an SIF of 1.00 is used for the sustained category at all points except bends, and the expansion category SIF’s are applied to the occasional category. By default this field is disabled for all applicable codes except B31.1-1967.
