Experirnental Study on Seisrnic Perforrnance of Bingharn Darnper

For enhancing seismic resistance of civil or architectural structures it is recognized to be effective to place dampers on them. Bingham damper has distinctive merit in independent nature from the velocity and the temperature， differ from conventional liquid type damper. In this study new type Bingham material are used and tested dynamicaiiy. As a test results， four different Bingham material showed good force-displacement hysteretic curves except one， which material exhibited so high viscosity and due to narrow clearance inner cylinder
