Parametric Study of Input Parameters of Soil-Structure Interaction based on Elastic Half-Space Theory
Authors: ,
Abstract: Foundations are necessary elements of all constructions. Over the years, a variety of foundation design procedures have been developed. This article deals with one of these methods, numerical modeling. Finite element method was used and has an advantage that allows us to simulate a real behavior of various phenomena and predict them. Currently there is no clear definition of the procedure that would be able to simulate the soil-structure-interaction with the sufficient precision. One of the reasons is that the input parameters directly affect the results. Understanding this phenomenon is crucial to maximizing the potential of this method. A parametric study that examines the effect of boundary conditions and the model size on the resulting deformation of soil-structure deformation was done. Series of numerical models with same parameters and variable of boundary conditions and dimensions based on the elastic half – space theory were constructed in Ansys to observe this problematic. The study proves that the influence of boundary conditions as well as dimensions affect the resulting deformation. The emphasis was put on examining the behavior of individual influences and their separation. Besides this the necessary size of the model is examined in this article.
