For a global structural analysis, we generate an extensive 3D model representation of structures simulating in-field conditions using structural analysis software packages in performing a thorough numerical analysis. Local structural evaluations are conducted with hand calculations using Mathcad, Depending on the complexity of the geometry of the structure or the non linearity of the material or loading condition a linear or nonlinear finite element analysis is performed using 3D continuum solid or shell elements to simulate the physics in play.
