Conclusion Static structural analysis has been done on the model with similar boundary conditions and the obtained

results have been assessed thoroughly. Being a beam with above 50m span it was inevitable to do a

nonlinear study with large displacement option turned on. The results seems to be on par with the static

results for a time of 10 seconds and 0.1 second time step.
