Modern pedestrian bridges tend to be long and slender in form, usually leading to a structural design with relatively low frequency primary modes of vibration. This type of structure can be excited to a nearly resonant response by various types of synchronized crowd activities and added damping is often required to prevent excessive structural motions and loadings. The three Spring Mountain Roa...

Over the past 10 years there has been a growing need to introduce closed-loop control technology for vibration suppression of buildings subject to wind or earthquake disturbances. This paper deals with the investigation of the effectiveness of a fuzzy logic based time variable damping tuned mass damper (TMD) on a building structure undergoing free and forced vibrations. The uniqueness of this a...

The hysteretic damping tuned mass damper (HD-TMD) is composed of a spring element, (HD) and mass. HD force proportional to the displacement (TMD). Recently, application HD-TMD has emerged, but its optimal design still lacking. To fill this academic gap, numerical solutions for parameters subjected white-noise excitation were obtained based on H2 optimization criterion. Performance balance with ...

This study considers a novel nonlinear system, namely cable-stayed beam with tuned mass damper (cable-beam-TMD model), allowing the description of energy transfer among beam, cable and TMD. In this vibration TMD is involved one-to-one-to-one internal resonance modes investigated when external primary occurs. Galerkin’s method utilized to discretize equations motion cable. way, set ordinary diff...
