Soil bearing capacity

Typical values of soil bearing capacity. For preliminary design purposes, BS 8004 [1] gives typical values of allowable bearing capacity which should result in an adequate factor of safety against shaer failure without accounting for the setllemenet criteria [2].

Bearing Capacity of 95% compacted fill

For a well graded crushed sand and gravel (road base) I've seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). We've compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg. Could use that to estimate bearing capacity.

Subgrades & Subbases for Concrete Slabs

The fact is that any soil or gravel base course is going to compress if the load is high enough, unless the slab is placed on solid rock. And in some ways that's good, because slabs curl and if the base can deflect a little, it can continue to provide support for the slab even when it curls.

3 Easy Ways to Tell if a Wall is Load Bearing

 · Often, these load bearing walls are roughly near the center of the house because the center of the house is the farthest point from any of the exterior walls. Look for an internal wall that's near the relative center of your house. There's a good chance this wall is load bearing, especially if it runs parallel to a central basement support beam.
