Study on Optimizing Design of Structural Rigidity of Super-large Span Continuous Rigid Frame Bridge Using ANSYS

摘要

In this paper, the situation of the midspan deflection of the span continuous rigid frame bridge is described, and the cause of the deflection is explained. It may be caused by the problem of the rigidity. Then the ANSYS is used to conduct analysis. The deflection of the biggest cantilever of the rigid frame bridge is the controlled target, and the optimizing design of the Sutong bridge is conducted. A meaningful result is obtained, and it provides a basis of the choice of the height of beams.
