STATIC AND DYNAMIC LOW CYCLE FATIGUE PERFORMANCE OF LOW YIELD STRENGTH STEEL SHEAR PANEL DAMPER

説明

The low cycle fatigue tests of low yield strength steel shear panel damper (LYSPD) are carried out under a constant amplitude sin wave to verify the ductility performance. Four shear strain amplitudes (20%, 30%, 40% and 50%) are applied to the LYSPD in the static and dynamic loading based on three kinds of periods (static, 2 sec and 1 sec). The hysteretic characteristic, fatigue life and failure mode are obtained and compared between the static and dynamic tests. Although the dynamic test results showed that the LYSPD has large deformation capacity as well as high energy dissipation ability and good low cycle fatigue performance, these characteristics are deteriorated with the high temperature caused by high strain speed and intemal friction. In order to evaluate the dynamic performance of LYSPD rationally, the strain speed and high temperature should be taken into consideration.
