The following FAQ was added for ADAPT-RC 2010
Does ADAPT-RC 2010 reduce the modulus of rupture by 0.5 for slabs and beams when using the 2004 Canadian code?
ADAPT-RC 2010 was modified to reduce the modulus of rupture, fr, by 0.5 for two-way slabs. This change is noted in the “Log_RC.txt” file in C:/Program Files/ADAPT/RC 2010. In a recent revision to the Canadian code (CSA A23.3-04/R2010) the modulus for all systems are to be reduced by 0.5. This change will be implemented in a future update to RC 2010.
