Sources for Frost Depth Values | Eng-Tips Hello all, this is my first post here so please bear with me Where do you go to find accurate frost depth line values? At my job, we often have to design footers foundations rapidly so as to get them to a costumer for the purposes of an estimate Because everything needs done ASAP, contacting
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
Frost line depth - Foundation engineering | Eng-Tips Hi guys! How many of you take in account the frost line depth while defining the foundation depth? Im asking this couse for my country wich is relativly warm, has mild winters rearly under 0"C for no longer then 7 days, minimum foundation depth is 80cm below finished ground level Converstaing
Purpose of thickened edge for concrete slabs on grade? Good Afternoon, I'd appreciate guidance on what the purpose is of a thickened edge for slabs on grade as well as what the design process looks like Many thanks for your help!
Floating slab on grade detail at exterior door | Eng-Tips I will probably continue to show a floating slab with an expansion joint between the slab and the typical exterior wall, and then show a downturn thickened slab edge bearing on either a short foundation stem wall (frost wall I guess you guys and or gals call it up north) or directly on the footing
Exterior Large Equipment Pad with deep frost depths - Eng-Tips Frost heave isn't really caused by just the moisture in the soil freezing (and the subsequent small volume increase) It becomes an issue when ice lensing happens This is when a horizontal layer of ice forms and continues to grow in thickness as water is drawn into the freezing layer through capillary action in the soil If you have non-frost susceptible soil (large granular fill), capillary
suitable cover for culvert pipe | Eng-Tips C1323 apparently is in frost heave country What is odd about this is I have seen lots of frost action (in northern states) and most of the time the land on either side of the pipe raises with frost action, but the culvert stays there The larger the culvert, usually the greater this difference In winter the roads have a dip at the culvert
Structural engineering general discussion - Eng-Tips Frost heaving occurs as a result of ice formation around small particles of soil causing an expansion in the mass This can occur in any location provided the soil or substrate below does not readily accomodate this expansion due to large void spaces
Stoops | Eng-Tips Stoops are any sort of entrance entity that is situated adjacent to building exits They serve two main purposes: 1 Provide proper surfaces to exit on, such as a landing, stairway, ramp, etc 2 In freeze areas, provide a deep enough foundation underneath to avoid frost heave and the resulting jamming of the door as it tries to open
