OVERALL TEST OUTLINE AND RESPONSE OF BUILDING WITHOUT DAMPERS

Realistic three-dimensional shake table tests using E-Defense were conducted for full-scale 5-story building specimens with/without dampers to evaluate seismic performance, under ground motions of a variety of scales ranging from minor to catastrophic levels. The building was tested repeatedly, inserting and replacing each of 4 damper types, i.e., steel, viscous, oil, and viscoelastic dampers. This paper focuses on the tests conducted without dampers at the end of the whole test series, and discusses responses and properties of the steel frame portion of the specimen.
