LOAD EXAMPLES OF SOIL
something is widespread belief that any land can support efficient lightweight construction, and therefore does not require a soil survey. However, the facts show otherwise. Residential houses and other buildings have been badly affected light due to ignorance of the characteristics of the subsoil.
the allowable load on a foundation is one that can be applied without causing damage to the structure, having a margin of safety given by the safety factor.
load capacity depends on soil type (gravel, sand, silt, clay or combinations thereof) of the characteristics of the foundation and structure, and the safety factor adopted. Knowledge of the presence or absence of groundwater level (NAF) is very important because it changes the conditions of resistance.
terzagui's theory is one of the first efforts to adapt to the mechanics of soils results of continuum mechanics. Terzagui theory covers the more general case of soils with "cohesion" and "friction" and its impact on soil mechanics has been of such significance that even today, is possibly the most widely used theory for calculating load capacity soil projects practical, especially for shallow foundations.
is important that the foundation rests on soils that are not subject to abrupt changes in volume due to changes in humidity (collapsible soils, expansive clays, fillers, etc..) So as not to generate unanticipated settlements.
------- FORMULAS AND DATA THAT HAVE TO KNOW ----
formulas that use THESE ARE: (DE THE THEORY OF TERZAGUI)
IS GOOD TO KNOW THIS:
qc = last load
adm q = allowable load capacity
