I found how CaesarII computed for Code stress is SIF is not equal to 1.0 but I doubt the answer.
sample
for node 25
Sa=5338.3
Sb=5851.1
St=554.6
Code Stress from CII=9789.6

SL= ((Sa+0.75Sb)2+(2St)2)1/2
SL=9789.6, thus it is consistent with Code stress for sustained case in CII output report.

but I find it strange, because SIF should intensify the stress not reduced?
