Seismic Performance of Continuous Monolithic Bridges

Abstract

The article highlights the issues of enhancing seismic resistance of transportation structures located in seismically active regions of Uzbekistan. Based on real earthquake records, the methodology for selecting bridge constructive parameters and performing structural analysis is examined. The study applies the Timoshenko beam model, spectral analysis, and time-history methods, with a case study of a reinforced concrete overpass in Jizzakh. Results indicate that post-tensioned tendons significantly improve seismic performance.
