Abstract

To explore the combined effect of mobile vehicles and moderate-strong earthquakes on the anti-overturning effect of curved beam bridges, a vehicle bridge seismic analysis model is established, and a vehicle bridge coupling vibration analysis method considering seismic effects is proposed for curved beam bridges. This research focuses on multi-span curved continuous beam bridges and analyzes the support reaction force and overall turning angle of the main beam during overturning caused by a combination of moderate-strong earthquakes and overload from eccentric vehicle loads. The study also investigates the influence of seismic motion type, peak values, and key vehicle parameters on the overturning stability of curved beam bridges. The results indicate that different combinations of vehicles and seismic loads can change the stress situation of the bridge. When three 100t vehicles with a longitudinal spacing of 2m are driving at a speed of 3m/s, the overturning of the three-span curved beam bridge is most obvious; Revise the formula for calculating the stability coefficient in the anti-overturning specification; Analyzed the eccentricity of the pier supports in a five span curved beam bridge and its impact on the anti-overturning stability coefficient. The calculation example shows that the maximum safe anti-overturning coefficient of the curved bridge is 1.55 when the two adjacent supports of the pier are set with eccentricity.
