초록
Diagonal reinforced coupling beam of coupled shear walls can provide sufficient strength and stiffness to resist lateral force. However, thereinforcement details for coupling beams required by ACI 318 (2011) are difficult to construct because of the reinforcement congestion andconfined interior area. This study presents experimental results about the seismic performance of coupling beams having bundleddiagonal reinforcement to improve the workability. Experiments were conducted using half scaled precast coupling beams having anaspect ratio of 2.0. It was observed that the bundled diagonal reinforced coupling beams can develop seismic performance similar to thecoupling beams with requirement details specified in ACI 318 (2011).
