Mr. Parrington,
Engineering & Technical Services engineers performed a minor design to determine the adequacy of the
slab under the two bearing walls provided at the address listed above.
Using the minimum loading requirements specified in the 2021 International Building Code to determine
the adequacy of the 6” floor slab with #4 rebar at 24” o.c. each way, having a compression strength of 4000 psi. The
maximum wall section loaded is at the 4’-0” section supporting floor and the stair stringer. The slab located below
the maximum loaded wall section is sufficient in supporting the applied load. The slab is also sufficient to distribute
the load to the soil below assuming a distribution load angle of 45°.
Note: - Loading: 2021 IBC
Vult = 115mph Importance Factor = 1 Internal Pressure Coeff. = +0.18 / -0.18
Loads:
Floor: Dead = 50psf Live = 50psf
Wall: Dead = 12psf
Soils: Maximum Allowable Soil Bearing Pressure = 3000 psf (per soils report)
- Seal applies to the slab adequacy below bearing walls ONLY .
Engineering & Technical Services, Inc. is not responsible for any construction or design that is not listed in the letter
above. The design is only adequate for the parameters and loading listed above, and may not be used for any other
projects unless approved by Engineering & Technical Services, Inc.
Our engineers are available for further consultation as may be required.
