Abstract Ductile coupled flexural walls are the primary seismic load resisting systems of many structures. The coupling beams of these structures must exhibit excellent ductility and energy absorption ability. To achieve better ductility and energy absorption than previously possible, the use of steel coupling beams with their ends embedded in the reinforced concrete walls is proposed. A comprehensive experimental program involving 5 steel coupling beams has been presented in a companion paper, and results from this program are used herein to study the effect of details of steel beams embedded in the reinforced concrete walls on seismic behavior of steel coupling beams. Significant strength increases were achieved using the auxiliary rebars and face bearing plates(stiffener plates located at the face of the concrete walls).
