Abstract
To study the mechanical performances of the small radius curve bridge of rigid-frame and continuous girder, a rigid-frame and continuous girder bridge with span arrangement (36+60+36) m is exampled and analyzed. A finite element model for the whole bridge is set up by BSAS, MIDAS and ANSYS. In view of the characteristics of the bridge with small radius and difficult conditions of construction, the paper conducts detailed analyses by focusing on the coupling effect of bending moment and torsion moment, rigidity, displacement and the stability. The results show that this bridge has enough strength, rigidity and stability.关键词
