Punching of column footings - comparison of experimental and calculation results

Abstract

The column punching through the slab is most often related to floor structures, and less often to foundation slabs under columns. Calculation models for these two problems are often not separated. The deficit of experimental results for column footings results in the use of floor slab models. A review of the theoretical and experimental research references, including Codes/Regulations for punching calculation of column footings, is presented in the paper. The experimental research program and its implementation is described. The results obtained are compared with calculation results based on various regulations. Recommendations and directions for future research are outlined.
