DUCTILITY ENHANCEMENT OF MODERATELY CONFINED CONCRETE TIED COLUMNS WITH HOOK-CLIPS
This paper describes an experimental investigation of the effectiveness of hook-clips in improving performance of conventional 90-deg. hook-ties and cross-ties in moderately confined reinforced concrete tied columns. The tie configurations provided in the 5 large-scale specimens tested included 90-deg. hook-ties and cross-ties, with and without hook-clips, and 135-deg. hook-ties. The columns were subjected to moderate levels of compression and cyclic lateral loads. The hook-clips were found to be effective in improving performance of concrete columns confined with 90-deg. hook-ties and cross-ties, resulting in the displacement ductility factor and energy dissipation capacity to be increased by roughly 85% and 400%, respectively.
