Abstract |
The purpose of this study is to secure the same or more structural performance and constructability for the details of hooks cross-constructedat 135 degrees used as external-ties standard detail in RC columns, therefore, to the purpose of improving constructability, the clip-type bindingimplement was suggested and A total of 28 pull-out specimens were prepared with the parameters of concrete compressive strength and clip-embededlength, clip installation location to examine the anchorage behavior of the clip-type binding implement. The experiment was carried out. The resultsof the experiment confirmed that the anchorage strength of the clip-type binding implement was higher than the details of hooks cross-constructedat 135-degree regardless of the diameter of tie and concrete strength, embeded clip length, clip installation. and The 90-degree end hook with clip-typebinding implement was showed a similar an anchorage behavior of 135-degree end-hooked transverse reinforcement, consequently, The 90-degreeend hooked with clip-type binding implement is evaluated to be the same anchorage behavior and performance as standard 135-degree end hook detail.
