A ridge-isolated tuned mass damper for seismic rehabilitation of a 3D structure under bidirectional earthquakes.
Efficient and practical seismic control of structures-particularly through isolation systems-remains a significant challenge due to high implementation costs and construction complexity. Moreover, their application in retrofitting existing structures often requires extensive modifications.To address these challenges, t...

High Mass Ratio Tuned Mass Dampers Obtained Through Building Superelevations for Seismic Retrofit
Tuned Mass Dampers (TMDs) are widely adopted passive vibration control devices used to mitigate structural oscillations induced by wind and seismic actions. Conventional TMD systems typically involve relatively small auxiliary masses installed near the top of tall buildings. This paper investigates an alternative strat...

Reinforcement learning-based adaptive gyroscopic control for torsional response mitigation: a proof-of-concept study
Torsional vibrations induced by seismic excitation can significantly increase structural demand, particularly in systems with geometric or stiffness irregularities. This proof-of-concept study proposes a hybrid adaptive control framework that combines passive gyroscopic damping with reinforcement learning (RL)-based...

Robust Optimization of Multiple Tuned Mass Dampers for the Offshore Monopile-Supported Wind Turbine
Offshore wind turbine (OWT) towers are continuously subjected to highly variable wind-wave excitations, where structural parameter uncertainties arising from manufacturing tolerances and material heterogeneity may significantly degrade vibration control performance. Conventional tuned mass dampers (TMDs), particularly...

Implementation and Numerical Validation of a Semi-Active Tuned Mass Damper for Vibration Mitigation in Lightweight Pedestrian Structures
The application of semi-active control systems in lightweight civil engineering structures is still limited even though several studies have shown an improvement in mitigating vibrations under uncertainty scenarios. In comparison with passive systems, a smart device is employed in a Semi-active Tuned Mass Damper (STMD)...

Integrated Active Vibration Control and Structural Health Monitoring of Flexible Spacecraft Panels
Abstract. This paper presents an integrated active vibration control (AVC) and structural health monitoring (SHM) framework for flexible spacecraft panels using offset piezoelectric stack actuators (OPSA). A three-dimensional ANSYS finite-element model of a hub–panel assembly with eccentric OPSA mounting is reduced to...
