| Popis: | Interaction between the soil and the structure is complex problematic. For the betterunderstanding of the behavior of the flat concrete slab in contact with the subsoil series of tests were performedin the Faculty of Civil Engineering in Ostrava in the Czech Republic. This article focuses on the fiber reinforcedconcrete flat slab with dimensions 2000 x 2000 x 150 mm loaded by vertical and horizontal force. This loadingis typical for building in undermined areas. The article describes the course, results, and evaluation of theexperimental test, which was performed on special test equipment Stand over a four day period. The slab wasexposed to a constant load of 100 kN in the vertical direction and about 50 kN in a horizontal direction. Thedeformations of the top surface of the slab were monitored by many sensors in both directions. Concretedeformation and cracks was also observed during the experiment. Deformation curves in the selected crosssection of the slab were evaluated from the measured data. Together with the experiment, the laboratory testswere performed from the same dough of concrete like the slab itself. The laboratory results are also present.The slab is compared to the vertically loaded slab with the same characteristics |
