Structural Optimization Design of Steel Tubular Arched Bridge Based on APDL

Abstract:

In order to optimize the structure of steel tube arched bridge, the parameterized model of steel tube arched bridge shall be established on the basis of APDL of ANSYS finite element. based on the huge computational power of ANSYS and the flexibility of APDL parameterization language, choose width of longitudinal beam, radius of arch ring and radius of suspender as design variables, regard maximum deflection and maximum stress as state variables, and take total volume as objective function. Realize structure optimization analysis of steel tubular arched bridge via parameterization computation.
