Realistic 3D-shake table tests using E-Defense were conducted for full-scale 5-story building specimens with/without dampers in order to evaluate seismic performance at ground motions of scales ranging from minor to catastrophic levels. The building was tested repeatedly, inserting and replacing each of 4 damper types. This paper focuses on the first test conducted with steel dampers. It discusses damper and building specimen, testing and table control methods, validations of test results, performance of the passive control scheme, and in- and out-of-plane bending of the steel dampers.
