Research on the work characteristics of reinforced concrete-steel encased wall joints with raft foundation
In response to the presence of wall or foundation damage in existing masonry structures with added raft slabs,a novel steel-encased wall-raft slab joint is proposed.The structural performance of this steel-encased joint and the conventional key-through-wall joint is investigated through scaled-model experi-ments,revealing that the steel-encased joint exhibits superior flexural and shear load-carrying capacity.Fi-nite element analysis is employed to investigate the load response of steel-encased wall-raft slab joints un-der different foundation parameters.The distribution of soil reaction at the bottom of the raft slab and the stress distribution in the wall are obtained for various foundation soil moduli and raft slab thicknesses.Fur-thermore,the failure mode of the steel-encased joint is analyzed.The obtained conclusions provide theoreti-cal references and engineering insights for similar foundation reinforcement projects.
