The paper presents a proposed framework to optimize the tuned mass damper (TMD) design, useful for seismic improvement of slender masonry structures. A historical chimney located in northern Italy was considered illustrate TMD design procedure and evaluate performance system. optimization process subdivided into two fundamental phases. In first phase, main parameters were defined starting from ...

To investigate vibration control and optimal design of transmission lines with tuned-mass-damper-inerter (TMDI), the motion equation TMDI is established in paper, closed-form solutions response spectrum line displacement are derived by frequency domain analysis method. The parameters optimized fixed-point theory, performance discussed. results show that increase apparent mass ratio has a positi...

-The performance of fuzzy logic (FLC) and PID controllers optimized by particle swarm optimization (PSO) for semi-active suspension system using magneto-rheological (MR) damper are investigated. MR damper is an intelligent damper filled with particle magnetic polarizable and suspended into a liquid form. The Bouc-Wen model of MR damper is used to determine the required damping force based on fo...

The Stockbridge damper (tuned mass absorber) is used on overhead transmission power lines to suppress wind-induced vibrations. These get exposed various types of wind motions that cause them vibrate and this causes fatigue failure at the suspension clamp where maximum stress occurs. Aeolian vibration most common motion eventually, lines. This paper presents study an asymmetric damper. A set exp...
