Study on Improvement for Seismic Behavior of Reinforced Concrete Shear Walls
Shear walls are commonly used as structural elements to resist earthquake. The seismic performance of shear wall can be guaranteed under small earthquakes, but problems exist when it is subjected to large earthquakes. To improve the ductility and energy dissipation capacity of shear walls in large earthquakes, shear failure must be avoided and the performance of plastic hinge region must be improved. The adaptive-slit shear walls (ASSW) is proposed in this paper The mechanical characteristics of ASSW satisfy the requirements of structures under different seismic level. Therefore the damage process of ASSW can be controlled and the ductile shear failure can be realized, which obviously improve the seismic performance of shear wall structures.
