Load-bearing capacity of integrity reinforcement depending on change of the mechanical parameters of the steel

The paper presents the results of numerical simulations performed on a simplified model of a slab-column connection. The aim of the investigations was to determine the value of the load at which the destruction of such a connection occurs due to a rupture of bars located above the column. In respective models, the column was situated axially or eccentrically with respect to span of bars. In each case the reinforcement passing above the column consisted of two bars. The analysis included a change in size, determining the most important parameters characterizing the properties of steel. The obtained results of calculations permitted to determine the relations between the exerted load and the displacement of the column. Based on the results, the load-bearing capacity of the reinforcing bars due to mechanical parameters of the steel was determined.
