Abstract
This paper examines the features of calculating the seismic resistance of a continuous monolithic highway overpass. The study focuses on a 120-meter-long three-span continuous monolithic highway overpass located in an 8-point seismic intensity zone in the city of Jizzakh, above the Tashkent-Samarkand high-speed railway line (Republic of Uzbekistan). The results of calculations for changes in normal stress in the upper and lower parts of the span structure elements of the continuous monolithic overpass, performed using the SHARK and MIDAS Civil software packages, are presented. As a result of the numerical calculation of the seismic resistance of the continuous monolithic overpass, taking into account the interaction between the soil and the foundation of bridge structure, it was revealed that the overpass retains its operational characteristics during an earthquake with an intensity of 8 and 9 points.
