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...

The need to design blast resistant civilian structures has arisen due to aggressor attacks on many civilian structures around the world. Achieving vibration and wave attenuation with locally resonant metamaterials has attracted a great deal of consideration due to their frequency dependent negative effective mass density. In this paper, metaconcrete, a new material with exceptional properties i...

The seismic response characteristics of a lead-rubber-bearing(LRB) base-isolated structure under rare and very earthquakes were investigated. acceleration, ductility coefficient, shear strain the LRB increase significantly in comparison to earthquakes; particular, may exceed ultimate cause damage structure. criterion selected for optimum tuned inerter damper (TID) TID–LRB hybrid control system ...

Tuned Mass Dampers are devices which can be assimilated to single-degree-of-freedom systems with a certain amount of moving mass, natural frequency and damping ratio intended installed on lively structures reduce the contribution mode their response. Once placed structure, movement mass damper couples structural response determines its properties as an isolated system becomes challenging. The a...
