Development of a seismic protection system on a road bridge passing the Chirchik River

Abstract

Bridges play a crucial role in ensuring the continuous operation of transportation systems, but strong seismic activity poses a significant threat to their stability. This article addresses the issues of protecting a bridge on the highway over the Chirchik River from earthquakes. Based on international and local regulatory documents, the study analyzes seismic protection systems including energy-dissipating dampers, as well as measures to reinforce supports and foundations. Additionally, methods for reducing seismic impacts are examined using the dynamic model of bridges, and effective design solutions are recommended. The research findings contribute to enhancing seismic safety on highways, ensuring the reliability of transportation structures, and minimizing economic losses in the aftermath of an earthquake.
