On the use of tuned mass dampers to suppress vortex shedding induced vibrations
Einar Strommen and Erik Hjorth-Hansen(Norway)rn

 
Abstract
    This paper concerns computational response predictions when a tuned mass damper is intendedrnto be used for the suppression of vortex shedding induced vibrations of e.g., a bridge deck. A generalrnfrequency domain theory is presented and its application is exemplified on a suspension bridge (wherernvortex shedding vibrations have been observed and where such an installation is a possible solution).rnRelevant load data are taken from previous wind tunnel tests. In particular, the displacement responsernstatistics of the tuned mass damper as well as the bridge deck are obtained from time domain simulations,rnshowing that after the installation of a TMD peak factors between three and four should be expected.
 
Key Words
