TEST STUDY ON MECHANICAL PROPERTIES OF SHEAR PANEL ENERGY-DISSIPATION COMPONENTS USING LOW YIELD POINT STEEL WITH DIFFERENT PARAMETERS

Shear panel energy-dissipation components using low yield point steel have a good energy-dissipation capacity, and the seismic property of structures using shear panel energy-dissipation components can be effectively improved. In order to investigate the influences of out-of-plane imperfection on the energy-dissipation capacity of shear panel energy-dissipation components, a traditional I-shape steel energy-dissipation component and three shear panel energy-dissipation components with out-of-plane imperfection were designed for the low cycle loading tests. The out-of-plane imperfection, the width of shear panel and the reinforced concrete constraint plates were the main parameters. Test results showed that the out-of-plane imperfection had significantly influences on the behavior of shear panel energy-dissipation components, and the reinforced concrete constraint plates effectively improved the energy-dissipation capacity of shear panel energy-dissipation components. The global buckling and local buckling of shear panel dampers could be effectively prevented by the flange plate and reinforced concrete constraint plates respectively.
