It is a project, the bridge name is Mike O'Callaghan-Pat Tillman Memorial Bridge and located in USA. all the data forces, pictures and free body diagrams are available to the public.This is what I am expecting:
1- Needs to write down all the assumptions that were made in the analysis.
2- Needs to assume that the arch is symmetrical and assume each member is linear instead of Curved to make the calculation very easy.
3- Free body diagrams and the equations that you used
4- Calculation of Force, Stress, Deflection, shear, bending and axial.
