Abstract:
This research looks into the possibility of carrying out the analysis and design of reinforced concrete silos using the finite element method and SAP2000. Sean grain reinforced concrete silo was taken as case study. The research was based on conducting a review of literature published in the field of analysis and design of silos, including the required data and the methods used for analysis and design. A pre-designed silo, of 8m height, 4m diameter used to store cement was used to check the finite element model and to confirm the possibility of using SAP2000. The accuracy of results was verified by comparing with the published results. They were in close agreements with maximum difference not exceeding 9%. The reinforced concrete Sean grain wheat silo which is of 15m height and 22.5m diameter was analysed using a model of shell finite elements of SAP2000 program. The silo was also manually analysed and designed to compare results. The comparison showed close agreement of the results and the difference did not exceed 6%. The additional important results and information that can be obtained from the finite element model are indicated presenting samples of them.
