Comparison of the Calculated and Experimentally Measured Values of Settlement and Stress State of Concrete Slab on Subsoil

Abstract:

At the Faculty of Civil Engineering VSB TU Ostrava testing device was constructed so that the phenomena of soil foundation interaction could be experimentally investigated and compared with numerical models. Results of experimental loading test are compared with soil foundation interaction analysis based on finite element method (FEM). The stress strain analysis of elastic halfspace by means of Gauss numerical integration and Jacobean of transformation is presented here. The arbitrary shape and general course of the loaded area in nodal points is allowed by use of 4-and 8-node isoparametric elements, numerical integration and Jacobean transformation. The objective of this paper is also improving and developing the soil-structure interaction analysis based on the experimental results and FEM.
