STATISTICAL ANALYSIS OF THE MODELS FOR ASSESSMENT OF THE PUNCHING RESISTANCE OF FLAT SLABS
Majtánová L., Halvonik J.
pages 330 - 333, full text

Flat slabs are one of the most widely used structural system for the construction of administrative buildings nowadays. Together with many advantages connected particularly with architecture and construction processes the system possesses also some drawbacks. From a structural point of view, the most dangerous is the concentration of shear forces at the vicinity of columns which may cause punching of a slab. Punching is a dangerous phenomenon due to its brittle mode of failure and its ability to spread over a whole structure, which can be followed by a progressive collapse. Several models for the assessment of punching capacity have been developed and calibrated using experimental results from laboratory tests. This paper deals with a statistical evaluation of the safety level of two models for punching resistance without transverse reinforcement. One of the models is fully empirical, the EC2 (2004), the second model reflect the physical nature of the phenomenon, CF CSCT (2017). Database which includes results of more than 400 experimental tests on flat slab specimens has been used for the statistical evaluation.
