Masonry Wall Accidental Eccentricity
Masonry Wall Accidental Eccentricity
(OP)
Curious what you guys use for this. The BCRSMS 2011 addresses this for columns as 0.1 times the column dimension but no mention is made for walls.
I have seen wall h/450 (h = wall height). So for an 8in wall 9ft high its h/450 = 0.24in vs 0.1*t = 0.7625in
I'm probably going to use the h/450 because along a length of wall the probability that the eccentricity is one way or the other 0.1*t along the entire length of wall is a lot smaller than the probability of the accidental eccentricity for a column. In reality I'd guess that for the most part the accidental eccentricity evens out if taking the average accidental eccentricity for the wall since it can go to either side, so h/450 seems reasonable.
What I'm curious is what YOU guys use typically and your reasons. Thanks :)

9ft of water's moment is a helluva lot higher than using either of these eccentricities but I was curious what everyone else uses for their eccentricity for my spreadsheet. My boss wants the wall reinforced but jeez reinforcing for 9 feet of water is insane.
Thanks again.
