摘要：
A reinforced concrete shear wall with concealed bracings has a series of advantages such as convenient construction, high bearing capacity, and ductility. Based on experimental study on six one-font reinforced concrete shear wall with concealed bracings under low-cycle load, the hysteretic loop curves were simulated and given the formula of key points by using the resilience mode. The resilience model has good simulation result, and it can show the seismic performance of the component pretty well, which lay a theoretical foundation for the elastoplastic seismic response analysis of the reinforced concrete shear wall with concealed bracings. Then, a regression model quantifying the stiffness degradation was proposed based on the stiffness degradation data using the MATLAB. The result shows that the horizontal displacement of shear wall is the result of its stiffness degradation, and the horizontal displacement of shear wall is mainly related to the shear span ratio and the axial compression ratio. © 2019, Editorial Office of Journal of Vibration and Shock.
