Heave can vary a lot from year to year depending on moisture conditions and weather. 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 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. 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. No, frost depth is not always required if what you are supporting can withstand the movement However, for most pipe racks we have designed we have gone to frost depth. Hi, guys, need help here However there is still some potential for frost heave, especially of there are variations in the soil
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. 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. Hello all, how can i determine the frost line depth for a project in virginia
All i can find in the code is in r301.2 which leaves in up to the locality The online version of the code is blank in this section Any help would be appreciated.
