Dynamic Tests On viscoelastic Dampers Directry Connected To Tension strings

摘要

Tension strings are useful for stiffening structures with minimum material, and act as compression members when pretension forces are introduced. If practical damping-system for these strings exists, they will enlarge design freedom by reducing and stabilizing structure's response against seismic or wind forces. In this paper, visco-elastic material with elastic spring is experimentally studied as additional damping-system connected directly to strings and keeping their pretension forces. The basic characteristics and effects of this damper are tested using real-size mock-up model, followed by checking agains theoretical values proposed by authors.
