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 incr...

bearing capacity prediction of axially loaded piles is one of the most important problems in geotechnical engineering practices, with a wide variety range of methods which have been introduced to forecast it accurately. machine learning methods have been reported by many contemporary researches with some degree of success in modeling geotechnical phenomena. in this study, a fairly new machine l...

In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

The change in project cost, or cost growth, occurs from many factors, some of which are related to soil problem conditions that may during construction and/or site investigation period. This paper described a new improvement method with minimum solution by using polymer fiber materials having length (3 cm) both directions and (2.5 mm) thickness, distributed uniform medium dense .sandy at differ...

The bearing capacity of closely spaced footings has become one the important topics in geotechnical engineering research owing to rapid development urban areas around world. In this paper, we propose three efficiency factors that can be used describe effects using Terzaghi’s traditional equation. With an advanced finite-element limit analysis upper and lower bounds, both strip multiple on cohes...

in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...

In the recent years, non-connected piled raft foundation has been considered as an economical and practical deep foundation in the situation that high shear and concentrated loads may occur at the connection of the raft and pile head. This paper was presented an experimental study of a square foundation on the effects of parameters such as S/D, L/D and etc. in two cases of connected or non-conn...

The type of soil known as expansive is capable changing its volume through swelling and contracting. These types soils are mostly composed montmorillonite, a mineral with the capacity to absorb water, which causes heave by increasing volume. Due their contract or expand in response seasonal fluctuations water content, these might prove be significant risk engineering structures. Many studies ha...

Determination of the pile capacity is always a major concern for the safe geotechnical engineering design. Different direct and indirect methods have been proposed for determining pile bearing capacity such as static and dynamic approaches. Each method depends on the condition of the soil and type of pile as well as accessibility to necessary information. In this study bearing capacity of drive...

Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...
