Examining the results of the experimental solution with a focus to elastic effect area

Abstract

Problematic of soil - structure - interaction is subject of research for many years, however satisfactory accuracy of numerical models has not been achieved yet. Therefore, it is necessary to examine this phenomenon. For this purpose, special testing equipment was built at Faculty of Civil Engineering in Ostrava and series of experimental tests were performed. One of the tested slabs was chosen and its numerical model was created in computational program Ansys 18.0. Numerical model consists of two parts - slab and soil, connected with a contact element. From the test and the model data, maximal deformations and deformations trough the cross section of the slab were compared. This paper examines whether the Hooke’s law is valid and can be used to express the test behavior and locate elastic effect area allowing linear modelling which can be useful for lowering computational time.
