Structural Damping


Structural damping of bridges needs to be specified in a wind resistant design code for examining their dynamic behavior against anticipated wind action. Because the dynamic response of bridges is generally evaluated by using the modal analysis, the quantity of structural damping has to be represented in terms of modal damping. The damping specification in the design code, therefore, is given in modal damping, based on the results of field measurements. The design and construction of long span bridges, such as Honshu-Shikoku bridges, have been continuously going on in Japan since 1970s. The modal damping data of long span bridges have been accumulated throughout this period by conducting field vibration tests, often just after completion of their construction, in order to verify the design assumption against the reality. At the same time, the modal damping data of medium span bridges have been also measured and accumulated by field vibration tests, since the field measurements are not only for the wind resistant design but also for the consideration of vehicle-induced dynamic responses. The structural damping values in logarithmic decrement are specified in wind resistant design codes by referring to these measured data, with the addition of some engineering judgments, since the theoretical evaluation of structural damping is very difficult at present.
