82. FULL-SCALE SHAKE TABLE TESTS OF 5-STORY STEEL BUILDING WITH VISCOUS DAMPING
Realistic simulations of earthquake responses were conducted in March 2009 for a full-scale 5-story building specimens with dampers using the E-Defense, the world’s largest three-dimensional shake table. The building was tested repeatedly, inserting and replacing each of 4 damper types, steel damper, oil damper, viscous damper and viscoelastic damper. This paper discusses the test method and test results as well as details of the 5-story building specimen. Performance improvement by the dampers is addressed for moderately tall buildings that constitute a major portion of the building stock.
