Height To Thickness Ratio Of A Reinforced Masonry Wall
Height To Thickness Ratio Of A Reinforced Masonry Wall
(OP)
I am designing a cantileavered reinforced masonary wall. What is the maximum height to thickness ratio allowed by the code for this type of wall? Where may I find a code reference to this issue?

I am not aware of an absolute maximum ratio but statically, you can't avoid having a very thin wall and make the wall work out as height increases.
Out-of-plane slender wall design at strength level is in Sec 2108.2.4.

Thanks for the reply. I will give you a little more detail of the wall I am designing. The will is a free standing cantileavered firewall exposed to wind load only. In this case for the h/t value. Would the "h" value have a multiplier of "2"?

I agree with Dave that h/t is not an issue with a freestanding wall. Disgrgarding the h/t, design the wall first and see that h/t comes out to. Regardless of the height, you would use a 6" wall at a minimum, probably a 8". In the end h/t wont look so bad.

I think code (ASCE 7-98) does not allow 30% stress increase in wind load combination I am not sure about ACI-530. Any comments ?
for a cantileavered wall effective height h'=2h
