摘要

Abstract

This paper systematically discusses the seismic performance and applicability of bridge structures under different seismic environments

aiming to provide theoretical basis and practical guidance for the seismic design of bridges. By reviewing the research results of scholars on eight types of typical bridges

such as double-column self-resetting bridges

beam-arch collaborative system bridges

and steel-tube concrete bridges

and combining the methods of finite element modeling

dynamic time-travel analysis

and scaled-down test

the mechanical response and optimization paths of the different structural forms under seismic effects are revealed. The study shows that the optimization of prestressing and aspect ratio of double-column self-restoring bridges can improve the seismic performance in high intensity zones; the beam-arch collaborative system bridges have both stiffness and durability under complex geological conditions; and the steel-pipe concrete structure significantly enhances the ductility and energy-consuming capacity of low piers and columns in steep-slope terrains. In addition

the study points out that there are limitations in the current seismic evaluation

such as oversimplification of models and single input of ground shaking

and proposes future research directions

such as refined modeling and multi-hazard coupled analysis.
