Based on the Winkler foundation beam theory, the effect of foundation width on the foundation beam rigidity and, in consequence, further on the load distribution in grillagefoundation are discussed.
A method of topology optimization of grillage structure with stress constraints is presented and applied to analyze the reinforced beam of raft foundation.
