자동차 브레이크용 마찰패드를 이용한 SAFE 마찰댐퍼의 전단내력 연구

초록

Dissipating structural energy during an earthquake by damping devices is convenient and time-saving method to improve seismic performance of existing buildings. Friction damper is one of these damping devices and dissipates seismic energy through friction force created at the contact surface of solid bodies. As a damping device, friction damper has a great benefit because it behaves relatively stable and efficiently in the shape of a rectangular. Various types of friction damper has been developed and could be classified by its frictional material and working mechanism. Friction damper dealt in this paper uses brake pad developed for automobiles as a frictional material and acts in shear-type behavior. The Performance of brake pad for automobiles is modified with respect to durability and stability. Purpose of this study is to evaluate the performance of the friction damper when variables like initial temperature and sliding velocity are changed through experiment.
