The document summarizes a study that compares the lateral behavior of reinforced concrete and steel silos through finite element analysis. The analysis found that steel silos experience greater deformation and stress than concrete silos under equivalent lateral loads from wind or seismic forces. In particular, the middle portion of steel silos deform more than concrete silos. Non-linear time history analysis also showed steel silos have larger displacements and stresses. Graphs depict how displacement and stress in each material type vary with wall thickness. Reinforced concrete silos are preferable to steel silos for industries due to better performance under lateral loads.
