Connection Design at top of Basement Wall
Connection Design at top of Basement Wall
(OP)
I have a 9' basement wall, 6' retained soil. Zone 3, Vertical Condition (two story), Wind governs with a base shear of 291 plf. I have a 2x6 sill plate connected with 1/2" anchor bolts at 3' o.c. I have floor joist at 12" o.c connected to the rim joist with simpson lpt5 clips at 2' o.c. and simpson a34 clips at each joist to resist the shear. I have design my wall with quikwall for basement wall condition "at rest". The dimension of the stem are 8"x9', the heel is 1'x2', the toe is 2'x10' because I have a soil bearing pressure of 1000psf. The plan checker says I need to add the 60 pcf of soil to the base shear, but the five other engineers in my office say that this is wrong.
What am I missing?

If you are using IBC the 60 PSF loading from the ssoil comes from
Table 1610.1 (c) For relatively rigid walls, as when braced by floors, the design lateral soil load shall be increased for sand and gravel type soils to 60 pounds per square foot per foot of depth. Basement walls extended not more than 8 feet below grade and supporting flexible floor systems are not considered as being relatively rigid walls.
Your 9' height precludes you using the exception.
