Prediction of bearing capacity of shallow strip foundation: a case study in Binh Dinh-Vietnam

Abstract

The bearing capacity (BC) of a shallow foundation is an important parameter to design economic structures. This study aims to propose a safety factor for BC of the strip footings. By utilizing, several geologies to calculate the shallow strip footing of the mid-rise buildings in central Viet Nam. The bearing capacity of the foundation is first calculated using the different available methods such as Terzaghi, Meyerhof, Hansen, and Vesic theories. Then the three-dimensional finite element analysis of the foundation is performed using PLAXIS software. Results indicate that there is a clear difference in the bearing capacity from the theory and numerical model. Additionally, a safety factor is proposed for the design purposes of the shallow strip foundation.
