State of the Art and Development Trend on Dynamic Performance of Silo-Bulk Material System

In order to ensure the long-term safe of storage and work in the silo-bulk material system, the developmentSprocessSandScurrent status of silo-bulk material system were summarized and analyzed, from the effective mass of the content in the earthquake, the interaction effect between the silo wall and bulk solid, theSmechanics characteristics of silo under the seismic. Base on the current status of isolation and vibration reduction for silo-bulk material system, pointed out that further precise and systematic division of effective mass participation coefficients of silo-bulk material system under earthquake response should be the focused. In order to increase the aseismic behavior of silo structure, it must pay attention to enhance the application of this technology in the field of silo structures and establish a theoretical system of isolation and vibration reduction suitable for silo structures. At last, the development trend on dynamic performance of silo structure was also predicted in this paper.
