Analysis of Model Foundation Slab Focused on Strain Gauge Measurement

Abstract:

Interaction analysis between foundation structure and subsoil and credential assessment of stress in the subsoil and internal forces in foundation structure are discussed in research conferences and scientific journals in the long term. Since 2012 research team at Faculty of civil engineering VSB - TU Ostrava has tested a few slabs with dimensions 2 x 2 m with thickness from 0.12 to 0.2 m. Complex testing comprises measurement of slab deformations, stress in the subsoil and measurement of stress in foundation slab using strain gauges. Slabs were made of plain concrete, reinforced concrete, pre-stressed concrete and fibre concrete. In the paper there are particular test results of stress measured in the foundation structure. Measured values are compared with calculated values. Strain gauge measurement efficiency and optimisation is discussed.
