This research aims to eva‎luate an‎d compare the performance of structural control systems, including active, semi-active, an‎d passive control systems, in reducing the dynamic responses of multi-story structures. Structures of varying heights were investigated under different dynamic loading conditions, encompassing seismic excitations an‎d harmonic loads. Advanced finite element models were utilized for simulations using the specialized software Abaqus. The investigated control systems employ diverse approaches: the active system utilizes advanced control algorithms, the semi-active system employs adaptive dampers, an‎d the passive system relies on inherent structural energy dissipation mechanisms. Key performance eva‎luation criteria included the extent of reduction in inter-story drifts, floor accelerations, applied control forces, energy consumption, an‎d frequency response. Simulation results demonstrated the significant superiority of the active control system in reducing dynamic responses, including displacements an‎d accelerations. However, this superiority is associated with the requirement for higher control forces an‎d, consequently, increased energy consumption. The semi-active system established a suitable balance between performance an‎d economic considerations, achieving effective reduction in structural responses. In contrast, the passive system exhibited limitations in controlling responses under severe loading conditions.
