説明

type:text

This study investigates the mechanism of noise generation from the modular type joint in highway bridges and quantifies the effectiveness of countermeasures. A series of experiments was conducted with a full-scale model of the modular type joint, where the noise and vibration characteristics of the joint with and without countermeasures were investigated under a vehicle passage. The dynamic characteristics of the joint was also studied by the impulsive hummer testing as well as by the eigenvalue analysis with the FEM model of joint.
