Coulomb's friction low was used for
modeling of wall friction. An incremental iterative finite element technique is applied for dynamic analysis of
wheat silos using SAP2000 structural software package. In this research seven reinforced concrete silo models
with different height to diameter ratios were studied and analyzed in time history by using earthquake
acceleration 0.5g applied to silos models. The resulting finite element silo pressures as the silo is full with and
without earthquake excitation are compared with theoretical filling and discharging pressure. The result
obtained revealed that the elevated silos response is highly influenced by the earthquake characteristics and is
depending on the height to diameter ratio. Also the findings indicate that the squat silo (large diameter and
height) are more resistance to the earthquake and more economical. The seismic responses of the elevated wheat
silo such as top displacement, normal forces, shearing forces and bending moments in silo support have been
assessed for earthquake records
