Get price25.1 INTRODUCTION. For small spans say up to 3.75 m in width, which are not subjected to heavy loadings, a simple slab may suffice. When the ratio of the length of a room to its breadth is greater than 2, most of the load is carried by the short span (i.e., the width the room) and as such the slab is designed to span along the width of the room as a one way slab.

Get price· One way and Two way Slab Design Aspect The slab provides a horizontal surface and is usually supported by columns,beams or walls. Slabs can be categorized into two main types: one-way slabs and two-way slabs. One-way slab is the most basic and common type of slab. One-way slabs are supported by two opposite sides
