ABSTRACT
ABSTRACT: The European Standard for the design of concrete structures with the use of non-linear methods shows a deficit in global reliability for cases, when the concrete columns fail by the stability loss before reaching the design resistance in the critical cross-sections. The buckling failure is a brittle failure which occurs without warning and the probability of its formation is markedly influenced by the slenderness of the column. Here the presented calculation results are compared with results from the experiment which was carried out in cooperation with STRABAG Bratislava LTD in Central Laboratory of Faculty of Civil Engineering SUT in Bratislava. The following paper aims to compare the global reliability of slender concrete columns with a slenderness of 90 and higher. The columns are designed according to methods offered by STN EN 1992-1-1: namely, a general non-linear method and methods based on nominal stiffness and nominal curvature.
