Characteristics of Local Vibrations in the Composite Members of Plate Girder and Rigid Urethane

When the composite member of I-section steel member and rigid urethane vibrates, the independent modes of the rigid urethane are generated at high-frequency region and the such modes are supposed to give the vibration reduction effect. In this paper, natural vibration analyses on local vibration of...

Summary:When the composite member of I-section steel member and rigid urethane vibrates, the independent modes of the rigid urethane are generated at high-frequency region and the such modes are supposed to give the vibration reduction effect. In this paper, natural vibration analyses on local vibration of the composite members are carried out and the characteristics of the independent modes of rigid urethane are clarified. The discrete model which is the combination of finite strip method and finite prism method is applied and the parametric analyses of dimensions and material values of the rigid urethane are carried out. Based on these results, the boundary frequencies which generate the independent modes of the rigid urethane are obtained.
