Abstract
In view of the mechanical characteristics of side pier in long span and low pier continuous rigid frame bridge, combined with the advantages of concrete filled steel tubular structure, we propose for the first time as pier of such rigid frame bridge, and carry out the corresponding research. Taking Weihe it bridge as an example which is an eight span continuous rigid frame bridge, by the finite element software Midas civil, we comparatively analyzed the steel tube concrete piers and reinforced concrete piers in adapting to the upper structural deformation, the internal force distribution,the amount of material. The results show that compared with the reinforced concrete piers under the same conditions, the steel tube concrete piers have smaller anti-push rigidity, better ability to adapt to the upper structural deformation, more balanced structure force, less material consumption, and lower project cost. By comparing the maximum horizontal displacement at pier top of two kinds of pier with different heights, we pointed out the reasonable application scope of the steel tube concrete piers.关键词
