Calculation of Presumed Bearing Capacity of Shallow Foundations According to the Principles of Eurocode 7

Abstract

15004-1989 [16] allowed for the use of a so-called "permissible bearing pressure" for preliminary dimensioning, and for foundation design in case of buildings with low importance. With this method, the central, vertical limit load of strip foundations and column footings with a given geometry could be obtained by applying the permissible bearing pressure along with shape and depth factors. In the light of the popularity of this method, and given that EC7 allows for employing design methods based on prescriptive measures, the authors have developed a new calculation method which conforms to the principles of EC7 and which is similar to the former method.

Probabilistic Analysis of Shallow Foundations on c-φ Soils Using 2nd Order Response Surface Methods

“…When performing reliability studies of shallow foundations, it is to be noted that the choice of the deterministic model of ultimate bearing capacity (see e.g., [19][20][21]) in order to determine the reliability index of foundation is crucial. As a matter of fact, probabilistic analyses used in conjunction with Terzaghi's Nγ bearing capacity factor constitute a formidable numerical task because derivatives for variances by first-and second-order methods are laborious, not to say extremely difficult (e.g., [5,22]).…”

A comparative study of soil-structure interaction in the case of frame structures with raft foundation

“…The analysis was performed assuming four different homogeneous soil types to examine the effects of different soil properties. The analysed soil types and their properties are summarised in Table 1 [11]. In order to investigate the effects of different parameters, a parametric study was carried out on two types of soil models: linear elastic-perfectly plastic (Mohr-Coulomb, MC) and nonlinear isotropic hardening (Hardening Soil, HS) material models [12,13].…”
