Retaining Wall - Stem Reinforcement distribution
Retaining Wall - Stem Reinforcement distribution
(OP)
I am reading one article about desigining a concrete retaining wall.
The As required for Stem is As: 2.26 in² per 1 foot.
Author use #9 each 4.5" (Center to Center)

Why AS is equal to 2.67?
As required is 2.26 in², so he should be using 3 #9 (3 in²)each 1 foot.
Any explanation?
Thanks and Regards

But I can't tell you why he didn't use #9 @ 5" = 2.40 in^2, greater than required.
RE: Retaining Wall - Stem Reinforcement distribution
I am confused how to distribute the reinforcement in the stem.
I draw this to show you how I am distributing the reinforcement:
Is this the correct or not the proper way?
The reinforcement is 2.2 in² per 1 foot, so if I use 2 # 9 per 1 foot, the reinforcement area is just 2 x 1 in² = 2 in².

But this spacing is along the length of the wall, not across the width. Not sure what you are dimensioning as 12".
RE: Retaining Wall - Stem Reinforcement distribution
OP, try avoid decimal bar spacing, and provide number of bars can be spaced equally in a 12" strip [Bar Space = 12/(#Bars+1) = whole #].
