A passive structural control system for seismic resistance of shear wall structures with application

摘要

A vertically slit shear wall is proposed based on the principle of structural control. Firstly, the shear-friction tests of energy dissipating devices in the vertical slit were carried out to study the energy dissipating mechanism of the devices, and a method of the calculation of the force-displacement skeleton curve is presented accordingly. Then single-storey slit walls and solid walls were tested under cyclic loads. The failure mode and energy dissipating mechanism of the two types of shear walls are compared. The force-displacement skeleton curve is calculated, which is in agreement with the test curve reasonably. Next, the shaking table tests of two slit shear wall models with different kinds of energy dissipating devices were conducted, which verified that the slit shear walls have favourable seismic performance. Lastly, an example for engineering application of slit walls is briefly introduced.
