Abstract
According to Model Code 2010 (2011) and EN 1992-1-1 (2011) the longitudinal reinforcement ratio of reinforced concrete columns should not exceed a value of 8%. Several national annexes to EN 1992-1-1 (2011) allow the use of higher longitudinal reinforcement ratios up to 12%. Concrete columns with reinforcement ratios larger than 8% offer new opportunities. On the one hand they permit higher load-bearing capacities with constant cross-sectional areas, on the other hand they allow smaller cross-sectional areas with constant load-bearing capacities. Examples from practice and research prove that detailing and casting of such highly reinforced concrete columns can be contrived. In order to review present limitations and to enhance the existing construction methods, experiments on highly reinforced concrete columns with bundled bars and large diameter bars are currently carried out at the iBMB, Division of Concrete Construction of the TU Braunschweig. This paper reflects the current state of research and covers the results of six column tests with longitudinal reinforcement ratios up to 25.6%. Test specimens and test setup are going to be presented, as well as the backgrounds that led to their determination. Furthermore the most important test results, such as load-deformation and post-fracture behaviour, are going to be illustrated and discussed.
