Abstract Shear wall system is one of the most commonly used lateral load‐resisting systems in high‐rise buildings. The reinforced concrete (RC) walls studied herein are composite shear walls (CSW) with multi‐embedded steel sections (MSS) at wall boundaries as well as wall middles. In this paper, experimental studies of CSW with MSS are presented and discussed. Sixteen 1/3‐scale specimens with varied structural parameters were tested under static loading and the effects of the parameters on the seismic performance of CSW were studied. It is found that the practice of MSS in RC walls is a good way to improve the structural ductility. CSW with MSS has better energy dissipation capacity than that with steel sections only at boundaries. MSS did not affect the final failure mode of the CSW, but they would restrain the development of cracks and prevent the concrete from serious spalling. For MSS, more steel area configured at the end columns will result in better seismic behaviour of CSW. Copyright © 2010 John Wiley & Sons, Ltd.
