Abstract: |
In Europe high performance concrete has been used successfully since 1990. The extremely high compressive strength of this material allows considerable reduction of cross-sectional dimensions of reinforced concrete columns and accordingly fulfils highest architectural and functional requirements. This leads to extremely slender members and therefore increases the risk of failure due to loss of stability in many cases. Because of the positive experience with high performance concrete up to now, the current study questions current conservative design provisions. In this context code procedures of Eurocode 1 [3] as well as Eurocode 2 [4] are compared with the results of probabilistic analysis and potentials for optimization will be indicated. |
