S.no Beam Slab
1. It is a linear structural element where perpendicular loads known as flex load are applied along with the axis. It is a flexural component that distributes the load horizontally to one or more directions within a single plane.
2. A beam is the most common example of a structural element in bending While the resistance to bending of a slab is similar to that of a beam, it differs from that of a comparable series of independent beams in continuity in both directions.
3. It is the most direct solution to the most common structural problems of transferring horizontal loads of gravity to the load elements. A slab is used when concentrated loads result in a perpendicular bending located in the first direction of extension causing torsion in the slab.
