The section design method of slab strips for reinforced concrete and post-tensioned concrete slabs is discussecl in detail. The method is practical, which simplifies an infinite number of locations in a slab into a finite number of cross section that can integrate the moments and stresses along the length of each design section to make the section results consistent with the prevailing building design code. It will be applied in more and more projects for it is clear in physical meaning, high in analytic precision and wide in field of application.
Keywords:  section design method; slab strips; finite element method; reinforced concrete slabs; post-tensioning
