- Avg. Max. Frost Depth in South Carolina | Eng-Tips
Concur with blackwed, however assuming a frost depth of 6 inches anywhere in South Carolina is a typical, very conservative assumption The state currently uses IBC 2003
- Frost Heave Calculation | Eng-Tips
Frost heave can easily be several inches in northern states with frost-susceptible (silty) soils and a shallow water table or just poor drainage On the other hand, dry, clean, sand or gravel may freeze without heaving Heave can vary a lot from year to year depending on moisture conditions and weather
- Top or Bottom of Footing? | Eng-Tips
Frost depth always has been and should be to the bottom of the footing You are trying to avoid a condition where frost occurs in the soil directly under a footing and in which case the soil expands (or rather the moisture freezes and expands within the soil matrix) and dislocates the footing
- Can foundation weight allow avoidance of frost depth? | Eng-Tips
A contractor is suggesting the use of 1ft deep, very wide concrete slab to support heavy rotating equipment The local jurisdiction has a required frost depth 42in Can a very heavy foundation (while still below the allowable bearing capacity of the soil) eliminate the need to go below the 42"
- Crushed stone size limitation for non-expansive frostfree fill
Hi, Guys, Need help here I remember there was a thread before, which discusses about the crushed stone size for use as non-expansive frostfree fill But I
- Which soils are most susceptible to frost heaving? | Eng-Tips
However there is still some potential for frost heave, especially of there are variations in the soil As mentioned in the other thread, would be best to insulate footings having inadequate cover (side of wall below grade and laterally over footing) to maintain soils thawed under footing
- Drilled Pier Frost Heave | Eng-Tips
Hello, I am currently designing concrete drilled piers, and per the geotech report, the recommendations incur a 1600 psf design stress for potential frost heave The recommendations also state that placing friction reducing material can be considered as an alternate option to prevent damage
- How is frost depth determined calculated? | Eng-Tips
If frost depth is determined for a county, how many tests do they perform before the county is satisfied with their estimate of frost depth? Is climate change taken into account in frost depth calculations? It seems to me that there are a ton of variables that could affect frost depth, so am just curious how these numbers are typically determined
