Estimation of damping in suspension bridges

In this paper, sources of damping data and the accuracy of measurement methods are examined. Methods of energy dissipation in components of the structure are evaluated to help explain the observations and to provide a basis for rational prediction of values. Data derived from full scale tests carried out on 28 bridges are presented in tabular form. (A)
