Abstract
In the connection of green frame, the bottom rebar of the precast concrete beam needs joint or anchorage to ensure structural integrity. However, given the characteristics of composite precast concrete joint, enough length over which rebar can be anchored or lap-spliced is not secured. In addition, due to issues with constructability, cost or quality, it is difficult to apply welding or mechanical connection techniques. Therefore, this study analyze the requirement for a bolt-type rebar coupler as a solution for the coupling issue between the lower rebars of green frame beam. The requirement for bolt-type rebar coupler proposed herein will provide basic data for development studies of the rebar coupler.
