Abstract
The purpose of this study is to secure the same or more structural performance and constructability for the detail off hooks cross-constructed at 135° used as external-ties standard detail in reinforced concrete columns, therefore, to the purpose of improving constructability, The clip-type binding implement was suggested. the experiment on the constructability evaluation and cost analysis of the clip-type binding implement by 90° end-hooked transverse reinforcement in reinforced conrete columns was carried out. The results of the analysis confirmed that standard detail column took about an one hour regardless of the diameter of tie. When using the clip-type binding implement, It was reduced to about 50% of the standard detail column. and regardless of the building size, it was most effective for the cost down when using the clip-type binding implement 1ea, it was about 32% fo labor cost reduction effect in comparison with using standard detail. as a result, Using the clip-type binding implement is shown be very effective in the working time and construction cost reduction.
