When it comes to construction terms, they are so difficult to be explained and understand if there is no image. Here we found perfect image presentation that will help you understand what is one way and two way slab. If the slab is supported only on two opposite sides that is one way slab. If the beam is supported on all four sides than it depends on span on slab that weather it is one way or two way slab.When the ratio of longer span to shorter span is greater than 2, than we assume that slab is one way slab. If the ratio of longer span to shorter span is less than 2, that slab is two way. Main reinforcement is needed in both directions in case of two way slab. The link and the images will help you understand better.
