Seismic surface wave protection of the administrative building of Namangan State Technical University using a tire-filled barrier

<jats:p>Seismic surface waves affecting the administrative building of Namangan State Technical University were numerically modeled using PLAXIS 3D. Displacement, velocity, and acceleration amplitudes at selected points were evaluated, and the reduction of structural vibrations with a seismic barrier was analyzed. A 1 m thick and 3 m deep tire-particle seismic barrier was placed along the foundation perimeter. The results showed a significant decrease in surface-wave amplitudes, confirming the effectiveness of the proposed protection method. The findings demonstrate that seismic barriers can effectively improve the seismic safety of buildings in active seismic regions.</jats:p>
