다중 슬림형 감쇠장치의 개발 및 성능 실험

Abstract

For the vibration control of residential buildings, a multiple type slim damper system is developed and dynamicperformance test is performed in this study. In conventional damping systems, larger installation space is required in order to achieveacceptable seismic performance, and as a result, it is difficult to determine efficient damping capacity of the device. The proposeddamping device is composed of several small slim type dampers and linkage units. It can control damping capacity easily by changingthe number of the small damper. To evaluate the proposed damping device, three slim type dampers (single-type, triple-type andpenta-type) are designed and manufactured in real scale. Dynamic loading tests are performed by using the three manufactureddampers. From the tests, it is shown that damping coefficient is proportional to the number of the damper combined. Thus, test resultsvalidates the practicality of the proposed slim type dampers. applying nonlinear curve fitting technique, numerical model of thedampers are developed and presented
