Failure of Slender Concrete Columns of Loss of Stability

Abstract:

Experimental verification of global reliability of slender reinforced concrete columns from the regular concrete C45/55 and high performance concrete C70/85 was realized within the applied research of the Faculty of Civil Engineering at Slovak University of Technology in Bratislava (SUT). Production of test columns and samples was in cooperation with ZIPP Bratislava Ltd. Columns are designed in the way to collapse due to stability before the resistance of the critical cross-section is reached. The relative compression of concrete was scheduled about 1,5 ‰. For performed experimentally verified slender columns, the reliability of simplified and nonlinear design methods according to European standards was compared.
