"Rheological features such as creep or shrinkage result in deformation of concrete elements and structures. If the element cannot deform freely, internal forces develop. This situation is typical for foundation or floor structures where free deformation prevents the contact between the structure and subsoil. Once the tensile carrying capacity of concrete is exceeded, the element fails. In such cases, reinforced concrete elements are typically designed and used. It is also possible to use rheological sliding joints that consist of asphalt felts. Thanks to the specific response of the asphalt felts to the shear load, it is possible to decrease the friction in the footing bottom considerably. For those purposes, the laboratories of the Faculty of Civil Engineering, VSB - Technical University of Ostrava test now the advanced asphalt felts. The measured values provide the basis for calculation of constructions with the sliding joints. This paper describes the practical calculation of internal forces"@en . . . "Sekanina, David" .
