Numerical analysis of the experimental flat slab for the parametrical study
Majtánová L., Halvonik J.
pages 533 - 536, full text

Reinforced concrete flat slabs are frequently used structural members in building construction. One of the most dangerous form of structural failure of these system is punching of the slab by column. Two experimental slab specimens reinforced with a high amount of shear reinforcement that increased punching resistance over the concrete struts capacity were tested. The best way how to verify the reliability of standard model for the assessment of punching capacity is comparison of the resistance obtained from the experiments, with the resistances calculated according to the standard. To determine the reliability of the standards a large database of test results is required. However, from economical point of view, it is not possible to prepare so many tests in order to fulfill this requirement. The problem can be solved by non-linear analysis which is a tool that allows to substitute actual tests with theoretical ones. The paper deals with calibration of the numerical model of flat slab specimens using results taken from the experimental program. The task was to find the suitable nonlinear material model for concrete and reinforcement, choose the proper boundary conditions and the correct load application. The correct adjustment of the numerical model allows to carry out parametric study of flat slabs with shear reinforcement.
