摘要

In this research a new type of hoop with double right angle anchorage (so-called here double anchorage type hoop) is proposed. To prove the feasibility of this type of hoops an experimental program divided into parts was carried out. First, pullout tests were carried out on bars with double right angle hook, and the results were compared with bars provided with 90° (single hook), 135° and 180° hooks. Results showed that for the double anchorage type, the bars reached the tensile strength indicating that enough anchorage strength was obtained. In the next stage experiments on column elements, reinforced with double anchorage and welded closed type hoops, were carried out. The behavior of the specimens with double anchorage hoops and specimens with welded closed type hoops showed comparable behavior in terms of ductility and ultimate strength.
