Abstract
Based on the experiment of 14 steel reinforced high-strength concrete columns subjected to low cyclic reversed lateral loads, the main failure patterns of steel reinforced high-strength concrete columns under combining flexure, compression and shear force are obtained, and the influence of shear span ratio, stirrup ratio and grade of concrete strength on the hysteretic curve and ductility of steel reinforced high strength concrete columns are analyzed. Test results indicate that steel reinforced high-strength concrete columns have an ability to resist one more earthquake load, the seismic performance of which is super to that of reinforced concrete columns.
