Reinforced Masonry CMU wall with SBEDS
Reinforced Masonry CMU wall with SBEDS
(OP)
I have to designed an enclosed control room (15') to withstand a 3psi load with a duration of 40ms. After entering my inputs for a masonry wall with #5 bar in every cell filled with grout the program tells me it works (incident angle < 2 degrees). My gut tells me this is inadequate. Anyone else have these results?

Not sure I understand your loading criteria though. Are you saying a constant 3 psi for 40 ms and then drops to zero? I'm not familiar with any standard blast loadings that take this form, should be a peak pressure that dies out quickly and then goes into a negative rebound phase. If that 3 psi is your peak pressure and then dies off over 40 ms then what you have would very likely be overkill. 3 psi is pretty small peak pressure as far as blast is concerned.
