- Abstract:
- In view of the problem of the bridge deck ’s large deformation of a curved chord concrete filled steeltubular truss bridge,which is overpass over an electrified main line,bridge analytic software is firstly used tobuilt finite model to analyze the old structure. In combination with static test results,the reason of the bridgedeck ’s large deformation is discussed. Then in line with some principles of little effect below the railway oper-iou,coIILcL0u sate au easlIe,savng uvesuen,au euecuvey upovg ue unuge opetauou stae,the transformation plan is put forward. These plans are structure system transformation,strengthening trans-verse support and tension sling. The transformation steps are given too. Finally,the effect of transformation isanalyzed and evaluated. Through analysis,it shows that structure after transformation is safety and the deform-ation of the bridge deck and the cross beam is greatly reduced. The effect of transformation is significant.
