Abstract

Abstract

In order to investigate the seismic behavior of the damaged ＲC frames retrofitted with Y-eccentrically steel brace under low reversed cyclic loading，two one-bay，one-story test specimens of one-third scale were built and tested． The hysteretic behavior，stiffness degradation，plastic deformation capacity，ductility and energy dissipation capacity were analyzed． The results indicate that test specimens show large lateral stiffness and lateral strength，and also have good energy dissipation capacity． With the increase of the height of energy dissipation link webs，the lateral bearing capacity of the test specimens increased． However，the ductility and energy dissipation capacity decreased slightly．
- Y-eccentrically steel brace,
- energy link,
- damaged RC frame,
- hysteretic behavior
