Discussion on Finite Element Numerical Modeling of Composite Box Girder with Corrugated Steel Webs by ANSYS

摘要

With its structural advantages, composite box-girder with corrugated steel webs is more and more popular in its application. However, due to the materialsconcrete, steel webs and the external tendons that used in combination, this kind of structure deforms uncoordinated relatively, which results in difficulties in calculating. Finite element analysis is an effective method to solve this problem, thus in this paper we focus on discussing how to simulate the model of box-girder with corrugated steel webs, including choosing elements, choosing constitutive relationships, meshing etc., proving the modeling method is feasible by combining papers on modeling external pre-stressed concrete structure and modeling research on combining 3D SOLID elements and SHELL elements by ANSYS.
