This paper presents dynamic characteristics of newly developed lead bearing damper designed as to be installed in steel structures, on the basis of an experimental and the analytical investigations. The experimental investigation under dynamic loading condition, was carried out using a prototype specimen which consisted of lead plate, steel plate with square shaped projection (key) and holed plate. From the experimental result, a rheological model which consists of 3 elements has been proposed and the result of identification has been compared with result of equivalent linearization method. The damping characteristics of the damper have been discussed throughout both experimental and analytical results.
