Comparing bearing capacity factor Nγ of finite element method with analytical methods for sandy soils

Shallow strip footings are essential to carry loads from structures. Load bearing capacity factors can be calculated both by the field tests (plate load test) and numerically. Bearing main parameters that affect of any foundations. Nγ, one these factors, have significant impact. Increase in internal frictional angle (ϕ), causes enhance Nγ value. However, after ϕ value reaches 30°, dramatic increase is observed. This make values complicated. In this study, foundation on surface resting sandy soils were designed with a Geostudio 2012 software. Various width (1, 1.25, 1.5, 1.75 2 m) friction (29°, 31°, 33°, 35°, 37°, 39°, 41°) was selected. numerical (software) analytical methods. After, methods compared results obtained Results indicate that, Biarez 1961 has average while Terzaghi (1943) Michalowski (1997) maximum. analysis (finite element method) increased an also. Values finite method other when B = 1.25 m, biggest m.
