摘要

Earthquakes provide a substantial risk to structural integrity and operating efficiency, as conventional designs based on inelastic yielding can lead to considerable damage and extended post-event recovery periods. The seismic risk is significantly increased for high-rise structures and buildings located on soft soil, where complex Ground-Structure Interaction (SSI) may change structural frequencies and enhance dynamic reactions. Previous study has identified a number of passive control systems for earthquake resisting structure which include various type damper and base isolator devices is used to control seismic risk. They used number of seismic control techniques which include Fluid Viscous Dampers (FVD), Tuned Mass Dampers (TMD), and Tuned Liquid Dampers (TLD), whereas modern studies increasingly focus on combination methods and cost-effective isolation materials. This review paper will aiming the latest developments in advanced structural control and seismic mitigation techniques. It focuses on the critical need for vibration reduction in structures with large floor areas and high-rise buildings that are located on soft soil or are subjected to considerable dynamic pressures. By defining research priorities for enhanced damping and isolation approaches, the study ultimately aims to fill difference within theoretical modeling and actual implementation. Key findings establish that these technologies reduce structural deformation and seismic damage. The effect of SSI and subsoil flexibility is shown to alter damper performance and shift structural frequency, emphasizing the need for integrated design. It is demonstrated that VEDs and TLDs perform best when parameters are adjusted using Direct Displacement-Based Design (DDBD), and that affordable materials like Scrap Tire Rubber Pads (STRP) are effective for base isolation.
