Different Types of beams and slabs

Different Types of beam

Simply Supported Beam:
Simply Supported Beam is a beam which is supported at extreme ends. This kind of beam is called simply supported beam.

Fixed Beam:
Fixed beam is a beam which is fixed at both ends. This kind of beam is called Fixed Beam.

Cantilever Beam:
Cantilever Beam is a beam which is fixed at one end and free on other end. So, this kind of beam is called Cantilever Beam.

Continuous Beam:
Continuous Beam is a beam which is more than two supports. This kind of beam is called Continuous Beam.

Overhanging Beam:
Overhanging Beam is a beam which is supported at two points, but on the last end it is hanging. So, this kind of beam is called Overhanging Beam.

One Way Slab
One way slab is supported on two opposite side only thus structural action is only at one direction. Total load is carried in the direction perpendicular to the supporting beam. If a slab is supported on all the four sides but the ratio of longer span (l) to shorten span (b) is greater than 2, then the slab will be considered as one way slab. Because due to the huge difference in lengths, load is not transferred to the shorter beams. Main reinforcement is provided in only one direction for one way slabs.

Two Way Slab
Two way slabs are the slabs that are supported on four sides and the ratio of longer span (l) to shorter span (b) is less than 2. In two way slabs, load will be carried in both the directions. So, main reinforcement is provided in both direction for two way slabs.
