Abstract

The paper systematically analyzes the coupled vibration characteristics of the long-span dual-use arch bridges under vehicles, using the Caiyuanba Yangtze River Bridge in Chongqing as an example. The paper analyzes the structure characteristics and important role in urban traffic through the current development of dual-use arch bridges. The paper analyzes the main influencing factors and the strategy of modeling based on the fundamental laws of coupled vibration of vehicles and bridges. The paper integrates the national and foreign research achievements, and summarizes the current latest theoretical achievements and practical outcomes. The paper analyzes its dynamic response under the compression effects of highway and track loads through numerical simulation for the Caiyuanba Yangtze River Bridge. The paper discovers the vibration characteristics of the Y-shaped rigid frame and mid-span under coupled loads, and the effect of road surface roughness and the speed of the trains on the amplitude of the vibration. The paper discovers that dual-use arch bridges have strong nonlinear characteristics in the aspect of coupled vibration under complex loads. The structure with the steel-box tied-arch is beneficial in terms of force-distributing, while there is the stress concentration problem that should be overcome. The paper provides the fundamental theoretical support and practical reference on the aspect of the vibration control and structure optimization of dual-use arch bridges, with high application value in terms of practical engineering.
