shear strength of embedded anchor bolts in cmu
if i have anchor bolts embedded in a cmu wall (f'm=1500psi)that is fully grouted (grout f'c=4000psi), is it ok to use the shear strength values from 1997 ubc table 19-d for bolts embedded in concrete, rather than the values listed in table 21-e for bolts embedded in masonry? or do the values for masonry already take into account fully grouted units with higher strength grout?
i think your problems can be best answered by a question also.
who鈥檚 holding the grout?
i will use the values listed in bolts embedded in masonry, even if it is 1,000,000psi grout (just exaggerating).
for your second question, my answer is 鈥?perhaps they already consider a certain strength of grout but maybe not higher 鈥?
many thanks.
