Restrained basement Wall Design
Restrained basement Wall Design
(OP)
I am trying to design restrained concrete basement wall. i have 13 ft high wall. Soil weight is 125 pcf.
Angle of internal friction is 28degree.
I have to design this wall for Eq. fluid pres. @ 61 psf/ft.
I can get moment based on triangular pressure and design the reinforcement.
Now if i want to design the footing for this wall i can take total vertical load on wall footing and divide it by soil pressure and get the width of footing or i have to check stability ratio and sliding ratio sim. to retaining wall.
is there any book or example i can refer for similar case.

And your design methodology for the footing width is OK too. If this concrete wall is supporting any wood structure above as in a residence for example, the load from this needs to also be included in the design of the footing width too.

If you design the base as pinned then you only need to worry about sliding at the base, not overturning. If there is a slab present, you're probably ok to say that sliding is ok by inspection.
