Detailed Two way Slab design Excel .xls

Two-way slabs are slabs that are supported on four sides. In two-way slabs, the load will be carried in both directions, thus main reinforcement is provided in both directions for two-way slabs. The slabs are considered as spanning two-way when the longer  to shorter span length is less than a ratio of two. The bending of these slabs takes the shape of a dish-like form when loaded uniformly.

The coefficient method may be the simplest, easiest and the quickest approach for the design of twoway slab supported by edge beam on all slab sides. This method was provided in the American Concrete Institute (ACI) in 1963 to design twoway slabs carried by steel beams, deep beam, or walls.

The floor system is the major part of a building structure, and the selection of an appropriate system is vital in achieving an overall economic building. This brief will provide guidance to architects and structural engineers during the concept phase of the design for selecting a suitable flooring system.
