Numerical Analysis of Reinforcing Bars in the Support Zone of Central Slab-Column Connections Subjected to Eccentric Tension

摘要

The paper presents the results of calculations, taking into account a material model (isotropic reinforcement according to Mises), representing laboratory tests of additional reinforcement. Complying with PN-EN 1991-1-7:2008 (EC1) and PN-EN 1992-1:2004 (EC2) this reinforcement is applied in reinforced concrete slab-column structures in order to protect them against progressive collapses. Additionally, an analysis was carried out, considering, the effect of applying in the material model the true stress-strain curve. In the course of these experimental investigations the values of displacements caused by the exerted load were compared with the values of numerical calculations.
