Aiming at the equivalent thin-wall box,the modal experiments which included different viscous medium,different liquid mass and double-layer plate with different inner plate\'s distance were designed,and the corresponding damping ratios were gained.

Due to the particular structural style of the reinforced concrete circular silo with partition,its temperature stress is quite different from the ordinary one,while the code for silo design doesn t include specific regulations with respect to the problem yet.

This paper simply narrated the calculating process of the horizontal tangential internal force for wall of reinforced concrete circular silo with partition ,and discussed the selection of simplified calculation models for this silo wall.
