Long-term objective of rheological sliding joints research is to contribute to updating the existing computational methods for their design. Sliding joints are applied in foundation structure to reduce the friction which is caused in footing bottom due to horizontal deformation loading (e.g. effect of undermining, pre-stressing). Accuracy of rheological sliding joints design depends on knowledge of the mechanical properties of used materials. The most common material for sliding joint are asphalt belts, which are tested at Faculty of civil engineering using own testing equipment and temperature controlled room. Currently, series of measurements have been carried out so that the results could be used for the numerical modeling. This papers aim is to present possible approaches to asphalt belt sliding joint numerical modeling in foundation structure and summarize their advantages and disadvantages.
