In this paper, the elastic stability of reinforced concrete silo shell roof is analyzed using finite-element model.

According to the experiment based on the study of the natural vibration of 21 organic glass wall supporting group silos,the shifty regularity of the basic frequency of vibration and vibration model are studied,when the number of the silos,the position of the hole on the supporting part,stiffness of the building above top of silo,and the quantity of stored material change respectively.
