Abstract:
The results of an experimental investigation conducted on a commercially available high-strength concrete are reported. The study tested 12 reinforced concrete columns in concentric compression and measured creep and shrinkage properties of concrete. In the case of columns, the main test variables were the area of longitudinal steel and tie spacing. The experimental results are compared with other test data and present code recommendations. The results confirm previous findings and raise concern regarding the absence of ductility of tied columns made of high-strength concrete.
