The aim of this paper is to present the influence of the subgrade reaction coefficient modelling on the simple 3D frame. For simplicity, it was assumed that the construction was made on the square foundations on granular soil. The soil reaction coefficient is modelled by different expressions drawn by different authors. For this reason different values of the coefficient were obtained. In order to observe the behaviour of these coefficients for each author curve families are created. They give us the relationship between the dimension of the square foundations and the value of the reaction coefficient. The paper then follows the response of the characteristic structural framework to these impacts. [ABSTRACT FROM AUTHOR]

This paper provides an analysis of settlement of foundation plates using finite difference method, and is designed in the aim to prove how this method, implemented in our Matlab program code, will give results similar to those obtained with the finite element method, and to show that plate' settlements are less dependent on the change of modulus of soil reaction.

The paper analyzes the educational-research project based on the preferabilities of the teaching process and learning mathematics using ICT tools, which focuses on the teaching of complex numbers and interactive geometry. Some examples of analysis of the motivation and impact of ICT already exist within the wider literature concerning the educational outcomes and the potential use of ICT in classrooms and in extracurricular activities. This work is designed with the aim to explore the possibilities of implementing such models in the teaching of mathematics and more to explain the results of their use, and ways to enhance motivation for learning and learning outcomes.
