Sažetak

Most research is mainly focused on the border load strength of a reinforced concrete pillar made of a high strength concrete, but what about the bearing capacity of the damaged AB columns of concrete with a normal strength from the last century. In this article, an experiment of a strain test (deformation) was described in relation to the amount of the axial eccentric load, to the breakdown of the damaged reinforced concrete pillar. Through real values, a model has been developed which can predict the straining of the deflection in relation to the size of the axial eccentric load. After testing the function of strain stress dependence and the axial eccentric load, a correlation test using the χ2 test was performed. Through testing, it was found that there was no statistically significant difference between the real values and the values obtained by the mathematical model.
