Punching shear behaviour analysis of RC flat floor slab-to-column connection

Abstract

The paper presents information about theoretical investigations and based on computer modelling and analysis research methods of fiat floor slab-to-column joint behaviour for punching· obtained by authors. Mam pnnctples of calculation and design methods of fiat slab-to-column support under punching according to variety of internattonal design coded arc observed and compared. The design problems of beamless floor systems for shear Wtth bendmg are discussed. The set of variables, such as lateral flexural reinforcement, bending moment to shear force ratw, span-to-slab depth ratio and slab thickness to column depth ratio, which may have an influence on flat two-ways floor slab punchmg shear strength is established and computer modelling analysis methods are applied to investigate the problem.
