This makes sense and is along my line of thoughts. Logically to me it would make sense to cap the effective length at what TMS prescribes (i.e. length at half the wall height) or whatever other spacing governs, because the stress you would design wall for would be based on that effective length...
Hello everyone
If you have a wall footing supporting a CMU wall, how do you treat concentrated load distribution on the wall to get loading on the footing? I know TMS 5.1.3.1 lets you go down at a 2:1 slope up to half the height of the wall to get the effective length the concentrated load is...
Thanks for the response. To clarify, is the assumption that the thermal mass of the building prevents any ability for freezing underneath the slab on grade, or is some form of insulation put underneath both the slab on grade and isolated footings to prevent freezing?
Hello everyone,
I'm looking at a set of structural plans and trying to understand why the exterior footings need to be placed below the frost line, but the interior footings are able to be placed right below the slab on grade with no foundation pier. Is there a construction step that's done to...
Hello everyone,
I have some questions about a wall footing design example from the ACI design handbook (see image).
1. In general, how would you get the axial force effects from a wind load on the wall footing. My thinking is let's say you had 12-inch CMU exterior walls that are 20 ft tall on...
