Analytical Modeling of Nonlinear Behavior of Composite Bridges
Abstract
Various aspects of a general finiteelement program for the nonlinear analysis of steelandconcrete structures is described. The program accounts for the nonlinear behavior of concrete, steel, and shear connectors. Concrete is treated as an orthotropic nonlinear material. The concept of equivalent strain is used to establish independent stressstrain relationships in the directions of orthotropy. Steel is modeled as an elastoplastic …
