WHAT IS SLAB ? Slab is an important structural element which is constructed to create flat and useful surfaces such as floors, roofs, and ceilings. It is a horizontal structural component, with top and bottom surfaces parallel or near so. Commonly, slabs are supported by beams, columns (concrete or steel), walls, or the ground. The depth of a concrete slab floor is very small compared to its span. The forces transfer from slab to beams occur either in one way or in two ways. The total system completely counts on the geometrical dimensions of the slab. Slabs may be supported by columns only, in this case two way action will prevail. If the ratio Long side / short side < 2 it is considered as 2-way slab, and if Longer side to shorter side greater than 2 then it is considered as 1-way slab. The load transfer mechanism from floor slab to supporting elements for one way slab ...
