- Abstract:
- In view of the mechanical characteristics of side pier in long span and low pier continuous rigidframe bridge,combined with the advantages of concrete flled steel tubular structure,we propose for the firsttime as pier of such rigid frame bridge,and carry out the corresponding research.Taking Weihe it bridge asan example which is an eight span continuous rigid frame bridge,by the finite element software Midas eivil,we comparatively analyzed the steel tube concrete piers and reinforced concrete piers in adapting to the upperstructural deformation,the internal force distribution,the amount of material. The results show that comparedwith 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,lessmaterial consumption,and lower project cost. By comparing the maximum horizontal displacement at pier topof two kinds of pier with different heights,we pointed out the reasonable application scope of the steel tubeconcrete piers.
