Experimental and Numerical Analysis of Concrete Slender Columns by Stability Failure

Article Preview

Abstract:

The European Standard [1] for design of concrete compressed slender members shows a significant deficit in global reliability for the design method based on non-linear analysis. The experimental investigation at the Faculty of Civil Engineering SUT in Bratislava was planned for slender concrete columns made of different concrete strength classes - C45/55, C70/85 and C100/115. A basic aim of the analysis was to design concrete columns subjected to bending moment and axial force where the stability failure proceeds at the compression strain 1.5 ‰. The first of three series of experimental and numerical analyzed columns is presented in the paper. The experiments were realized at the Faculty of Civil Engineering SUT in Bratislava with cooperation of ZIPP Bratislava LTD Company.
