How to calculated deflection in Metal Frame due to load on shelves mounted on it.

Question : There are 3meter high C-Shaped MS Column at 0.5m apart and are fixed to floor and slab. On these C-Shaped Column, I am going to fix 5 or 6 Nos of Angle Bracket (200x300) along the height to support shelves on each column. I just want to calculate the stresses and deflection in Column due to the loadings on shelves.

Can anybody help me with calculation?
