Calculating The Transverse Force Of The Concrete Continuous Curved Beam Bridge Based On Lateral And Vertical Coupled Effecting

The typical disease in the operation process of concrete continuous bending bridge is the lateral climbing of the main girder,and the transverse force of the bridge is particularly important.In the past,scholars mainly analyzed the change and influence of vertical deflection of the bridge during the operation of the vehicle,but few scholars studied the lateral vibration of the bridge.This paper will calculate the transverse force of the bridge based on lateral and vertical coupled effecting.This paper analyzes the transverse force of curved beam bridge through the following work:1.A numerical analysis method for lateral coupled effecting is presented.In this paper,a 12-degree-of-freedom vehicle model is established and considering the lateral damping of the vehicle.And deriving the motion equation of the vehicle.Then the lateral and vertical coupled effecting model is established.Last,performing the dynamic response analysis.After that,the vehicle motion equation is derived and then the coupled vibration model is established to analyze the dynamic response of the vehicle.2.The calculation method of transverse force of curved beam bridge is proposed.In this paper,a 12-degree-of-freedom vehicle model is established and to consider the lateral freedom of vehicle.3.Considering the effect of road roughness on the transverse force of the bridge.In this paper,the transverse force of the bridge is calculated and the transverse force of the curved beam bridge is analyzed,respectively considering the pavement smoothness and the four kinds of pavement grade of A,B,C and D.In this paper,the transverse force of bridge is increased with the increasing of bridge condition.4.Considering the influence of lateral axle coupling vibration on lateral force.This paper through the establishment of the vertical axle coupling vibration model and the relation to the vehicle bridge coupling vibration model,and carries on the dynamic response analysis,the calculation the transverse force of bridge。The influence of the coupled vibration of transverse axle on the transverse force of curved beam bridge is determined.In this paper,the transverse l force of the bridge is obviously increased after considering the coupled vibration of the lateral.Therefore,it is necessary to consider the coupling lateral vibration of the bridge when the transverse force of the curved beam bridge is calculated accurately.5.In this paper,through the analysis of the model,considering the influence factors on the bridge transverse force,respectively,the influence of vehicle centrifugal force,the influence of the vehicle running on different lanes and the influence of vehicle speed.Through the analysis and comparison,drawing correlation time curve.In order to determine the effect on the transverse force of the bridge.By size to compare the influence of various factors,in this paper,the relation to the vehicle bridge coupling vibration model was optimized,and make it more realistic,precise calculation of concrete curved girder bridge transverse force provides reference.
