This manual does not contain, all the theory background regarding the calculation procedures carried out in code checking.

In case you need a deep knowledge of the theory concerning any of the calculation procedures used, we encourage you to jave a look at the bibliography to which the different paragraphs refer. Should you require any further specific bibliography, please feel free to contact your CivilFEM distributor. By default, the active units system is the International System of Units N, m, s. Table 2. III Div. CivilFEM materials have four different kinds of properties: General properties : Common properties for all kinds of materials Material properties : Reserved for steels, concretes, etc.

Specific material properties are always available for a particular material, regardles of the code under which the material was defined.

Illustration of the model adopted in this study. Results different cases considering most of the situations which are usually encountered in practice were modelled using the method described in the previous subsection, with the aim of studying the parameter IE eq. The settlements were calculated at the centre point of the foundation maximum settlement. Figure 3. Figure 4. This paper considers E as a variable for determining IE, which is novel as it has not been considered by other authors in the literature consulted.

Note that the values of IE proposed by Burland [9] and Janbu et al. Figure 6. Comparison of the IE values proposed by Janbu et al. Results analysis In the previous sections FEM models were run to study the effect of different soil parameters i. Regarding the IE values proposed by Fox [4] and Janbu et al. These differences are because these authors did not consider all effects of embedment on foundation settlement described in section 2.

However, there were some exceptions where the IE values presented in this paper were lower. These cases were: Similarly, Bowles [15], omitted the use of these methods due to the aforementioned underestimation of settlement that is less conservative.

From the analysis performed a relationship between IE and E not previously described in the literature was observed, in which IE slightly increases with greater E values.

In the following section an analytical relationship between IE and the variables which were found to affect it is proposed. Proposed formulae Based on the results shown in the previous sections, two different formulae are proposed for the determination of IE.

However, in the second formula E0 is considered as an additional variable. POLI-MODEL [34, 35] allows the generation of families of mathematical models with non-linear parameters based on the experimental data of the intervening variables.

The software, which automatically searches among different nonlinear models within the parameters, is based on the application of the Gauss-Newton algorithm for obtaining the parameters of nonlinear models. The expression obtained for the calculation of IE is: The formula dependent on E was also fitted to the results obtained from the modelling, giving a R2 of 0.

For higher values it is recommended that the limit values are considered, i. Note that the IE trend is asymptotic, similar to the curves proposed by others e. Case studies In this section a validation of the proposed values for IE is performed through 94 different case studies compiled by Burland et al. For this purpose, settlements were calculated using the most commonly used expressions proposed by Schleicher [33] and Mayne and Poulos [1], considering the foundation at the surface and correcting for the embedment effect using the IE values proposed by Janbu et al.

Then, these calculated settlements were compared with those measured in the field by Burland et al. Table 1 shows the most relevant results derived from the analysis performed. Note that eq. Regarding the IE values proposed by Janbu et al.

The application of the proposed IE values instead of that proposed by Janbu et al. Note that MRE was calculated relative to the main prediction method, which is in all cases the one proposed in this paper eq. However, for only 17 of the 94 cases i. Conclusions In this study three-dimensional nonlinear analysis was performed using the FEM to analyse the effect of foundation embedment on settlement in a rigid foundation resting on an elastic half space medium.

One of the most important developments is the high number of cases considered which was much higher than that considered in previous studies. Previous models proposed by other authors were also improved by considering conditions most commonly encountered in practice and all plausible variables and effects that determine the influence of the foundation embedment on the reduction of settlement.

The most relevant conclusions are summarized in the following paragraphs: A satisfactory FEM model was achieved by a previous study of optimization and a verification process, which showed the validity of the model used.

Two new formulae were obtained for calculating IE for all of the cases considered. The first proposed equation eq. However the second eq. For both cases the squared regression coefficients were higher than 0. The proposed IE equation follows a similar trend to that proposed by Burland [9]. However, IE values derived from eq. Regarding the values proposed by Fox [4] and Janbu et al.

A previously unknown dependence of the embedment influence factor IE on E was found by means of eq. IE values derived from eq. Consequently, it represents a considerable improvement for the prediction IE with respect to the most current most commonly used factors, providing a better alternative to the IE values proposed in literature.

Furthermore, the IE values proposed by Janbu et al. Terratest Rosehill supported part of this research. References [1] Mayne P, Poulos H. Journal of Geotechnical and Geoenvironmental Engineering.
