Vibration Reduction Effect of Constrained Viscoelastic Layer Dampers in Floor System of Steel Buildings
초록
영어
Steel structure with long span and lightweight materials may have low structural stiffness, so floor vibration response of the structure may increase by such as walking or impact load. The floor vibration response should be reduced by taking effective method, rather than increasing stiffness that causes enlarging the size of structural members. Increasing stiffness is easy way to engineers, but it cause section enlarging and heavy weight of floor system. Therefore, to increase the damping may be beneficial. In this study, after installing constrained viscoelastic layer damper in the steel structure, the vibration experiments were conducted using various loads; heel drop, jumping, walking. It was verified experimentally that the constrained layer damper was effective method for vibration response reduction to any dynamic load in floor system of steel buildings.
