Abstract: Considering the interaction of bulk solids and silo structure and its foundation, a systematic dynamic analysis of many kinds of cases to the bulksolid's different calculating model of silo structure, which is put on the elastic foundation, was carried out in the paper. The conclusion is made after a comparing with the testing results made by authors: To the horizontal impulse of foundation, the dynamic response of silo on elastic foundation is stronger than that of silo on rigid foundation; the relative motion between the silo wall and bulk solids has the effect of lightening the vibration of silo structure.
