This paper addresses the seismic performance of reinforced concrete coupling beams with various reinforcing details for a design alternative to simply the reinforcement details of coupling beam. The numerical analysis and test results showed that angle reinforced coupling beam exhibited a better stable behavior in comparison with non-diagonally coupling beams and sustained corresponding drift ratio, peak-to-peak stiffness and cumulative dissipated energy in comparison to diagonPally coupling beam.
