Development of replaceable self-centering energy-dissipation component for seismic resilient RC shear wall
A novel replaceable self-centering energy-dissipation component (RSEC), suitable for use in the bottom corners of reinforced concrete (RC) shear walls, is developed in this study. The constitution and fabrication of RSEC, and its design method are introduced. The mechanical behavior of RSEC is investigated through cyclic loading tests on six full-scale specimens with different energy-dissipation ratio and self-centering ratio. The experimental results show that RSEC has stable mechanical performance, and the hysteretic behavior of the components before and after replacement is basically the same. The energy dissipation capacity of RSEC increases with the increase of the energy-dissipation ratio while increasing the self-centering ratio can effectively reduce the residual deformation of the component. The numerical model for resilient RC wall with replaceable components is developed and validated. The seismic performance of RC shear walls with different types of replaceable components is compared by numerical simulation with the aid of this analytic model. The simulation results show that the proposed RSEC provides not only satisfactory strength and stiffness but also stable energy dissipation capacity and reliable self-centering capability for the structural wall. The RC shear wall with RSECs provides a promising solution for the improvement of seismic resilience of RC structures.
