Abstract
A structural damping can be improved by installing high damping alloy in steel structures. This paper presents a fundamental study to increase the structural damping by adding high damping alloy in the steel e structure. Free vibration tests using models composed of stainless steel plate and small Mn-Cu alloy plate, and vibration analyses for the test models are carried out to investigate damping ratios and natural frequencies of the complex platee structure. From the experimental and analytical results, the effects of installation positions and installation sizes of the Mn-Cu alloy plate on the damping ratios and frequencies of stainless steel plate are mode clear.
