Abstract

Abstract

Damping ratio is the main index representing the property of materials in reducing vibration. Free vibration method is employed to measure the damping ratio. A batch of fundamental data for the damping ratio of polypropylene fibre concrete in small deformation is obtained. The analyses of experimental results conclude that the testing method and procedure for damping ratio are reliable; for concrete in the same class, the damping ratio changes slightly with increasing polypropylene fibre; and Young's modulus decreases with increasing polypropylene fibre.
