Two design cases were introduced and checked with suggested approachs that design Irregular RC Slab based on FEM. Methodology for irregular RC slab design stated in this paper can be used as reference for other projects.Keywords：irregular reinforced concrete slab;foundation raft;finite element method; twisting moment design
