Description
This session walks you through a complete nonlinear static analysis of a reinforced concrete bridge pier using MIDAS FEA NX. You will learn how to import a 3D Parasolid model, define materials such as smeared cracking concrete and prestressing tendons, model longitudinal and transverse rebars, and apply real-world loads including braking force and prestress. The session concludes with interpretation of 3D crack results.
