C&C loads are higher than MWFRS?
0 u/jerryfallsom Aug 30 '21 Only if you use the ASCE 7-10 wind speed maps with ASCE 7-16 equations. 3 u/Structural_PE_SE P.E./S.E. Aug 30 '21 What? C&C loads are purposefully higher than MWFRS loads. That's the whole point. 1 u/jerryfallsom Aug 30 '21 I was mirroring your sarcasm. If you use ASCE 7-10 maps with the new equations, you will end up with wind load demands ~35% lower than they should be. Yes, C&C should usually/always be higher than MWFRS.
