In high-rise concrete structures, the elevator or stairs which located in the middle of the building are always put into the RC core walls. It not only meets the requirements of the function of usage, but also makes the core walls bear most of the lateral force and becomes the main component in the whole structure that resists the lateral force. Therefore, the seismic performance of RC core walls is of great concern to engineering. At present, there is little experimental study on measures of improving the seismic performance of RC core walls. In this paper, firstly, a new type of construction measure is put forward to improve its seismic performance. Secondly, through the experimental study on one 1/6 scale core walls with concealed bracings and one 1/6 scale normal core walls under the low cyclic loading, the effect of concealed bracings on bearing capacity, stiffness, ductility, hysteresis, failure phenomena and energy dissipation of concealed bracings are discussed. The experiment shows that the seismic performance of RC core walls with concealed bracings is improved remarkably.
