Shaking Table Test of a Full-Scale Bolt-Connected Concrete Sandwich Wall Panel Structure with Friction-Strip Coupled Damper
To improve the energy dissipated ability and reduce seismic deformation of the bolt-connected precast shear wall structural system, a friction-strip coupled damper that could provide sufficient energy dissipation for main structures was proposed to be installed at the toes of wall panel. To evaluate the seismic performance of the structural system, a shaking table test of a full-scale two-story model was conducted. Seismic capacities of the precast structure without dampers (Model I) and with dampers (Model II) were compared in the test. The results showed that the two models had the similar lateral stiffnesses, indicating the installation of a few dampers exerted slight effects on the stiffness of the structure. Besides, the two models underwent ground motions until to 0.22 g with slight damage, and indicated commonly high seismic capacity against design-basis earthquake. Compared with the Model I, the Model II showed a fewer inter-story drift ratio under the same PGA, which suggested that the friction-strip coupled dampers could effectively reduce the inter-story drift response of the structure.
