Abstract The purpose is to study seismic response and dynamic lateral pressure of the silo wall with different storage conditions under earthquake. FEM was used conduct time history analysis silo. empty smaller than that filled silos, for latter, action, bulk sand particles had a more complex interaction, nodes displacements on columns mainly fluctuated rising. For deformation sand, it similar parabolic pattern in section, closer center greater was, farther away from was. maximum acceleration near top silo, middle contact silos. Nodes overpressure coefficient 1.6 2.9 half fully respectively, but standardized value 2.0, therefore, suggested proposed. Meanwhile, Mises stress investigated, larger particularly around ring beam due interaction between wall, where stiffness sudden change, at increased gradually action.
