Resistance of Flat Slabs with Openings

Abstract:

Flat slabs - locally supported slabs are an important and preferred type of modern buildings structures. The column – slab contact point has the concentration of compression but especially shear and tensile stresses which may cause sudden failure – punching of slabs. The paper deals with the analysis of flat slab sample with two openings near the column - the typical example of real structures. The results are presented only for one size and location of openings. Material properties for analysis were obtained from experimental work carried out at the Department of Concrete Structures at STU in Bratislava. The phenomenon of the punching was calculated according EN1992 and Model Code 2010, and also numerically analyzed by nonlinear methods based on the finite element method. Results of these processes of resistance determination are compared separately for flat slab without and with openings.
