Slabs are the one of the most widely used structural elements whose depth is considerably smaller than rest of the dimensions. Basically slabs are used as roofs and floors in buildings, roof and bottom on water tanks, on bridges etc. Slabs support and transfer load i.e. Dead load and live load, to columns by shear, flexure, and torsion. Slabs also help in reducing the effects of lateral wind loads and earthquake loads. What is One Way Slab? One way slabs are the slabs in which most of the loads are carried on the shorter span. The ratio of longer span to shorter span is equal to or greater than two or when the slab is supported by beams only along two opposite sides slab then the slab behaves as a One-way slab. What is Two Way Slab? Two-way slabs are the slabs in which loads are carried on both of the spans. The ratio of longer span to shorter span is less than two and when the slab is supported by beams along all the sides then the slab behaves as a two-way slab.

4. What is One Way Slab?
In easier worlds one way slab are spanned in shorter side means
supported on the beams of longer side as shown in figure above. Because
of much greater length, longer side i.e.longer beam, carries most of the
loads compared to shorter side.

5. Where is one way slab used?
Generally one way slabs are used where longer
side is too longer than shorter side that is
waranda's.

6. One way slab reinforcement details
You can notice that alternate main reinforcement bars are bent-up near
supports at a distance of 0.1L from support, as per Clause D-1.6 of code,
to resist tension that can appear because of partial fixity of support.

8. What is Two Way Slab?
In two way slab as the floor load transferred in both directions, the flexural
reinforcement has to be designed in both directions.
