Analysis of Impact to Counter Force and Internal Force in Different Arrangements of Minor Radius Curve Steel Box Girder Supporting Point

Abstract:

The designing course of curve steel box girder always needs to consider the city roads and buildings.It make the bridge position not only span the traffic below,but also avoid the house building all around [1].So curve steel box girders always have bigger span,smaller radius and the settled pier position.Also,because of the light weight and the prominent effect of bending-torsion coupling [2],the supporting points of steel box girder often suspend under the improper designing.It impact the safety of bridge vastly.Seriously it can make bridges topple.This paper take the designing course of a minor radius curve steel box girder as background to research change law of counter force and internal force of steel box girder in different supporting point arrangement.
