Toe projection in Basement wall
Toe projection in Basement wall
(OP)
Hi all,
Is it a normal practice to give a toe projection in basement walls.
I have 4 level basement wall, the raft/footing for the baement wall is 750mm. When i run the safe analysis, the edge stresses are not very high.
Whatis the minimum projection of the toe in a basement wall? Is there any standard ACI practice?
A consultant is proposing a projection of 3ft, which i think is excessive, i would like to push for 100mm(4"-6" at most)
any thoughts or references , plz ??

I wouldn't put a lot of faith in some computer analysis for this corner. What I've seen is that the analysis overestimates the support effectiveness and under estimates the stresses.

Depending on the wall size, my normal footing width is 14" to 18" for residential and 24" to 30" for commercial.
