image GROUND FLOOR BEAM LAYOUT

A beam is a structural element that primarily resists loads applied laterally to the beam's axis. its mode of deflection is primarily by bending. The loads applied to the beam result in reaction forces at the beam's support points. The total effect of all all the forces acting on the beam is to produce shear forces and bending moments within the beam, that in turn induce internal stresses, strains and deflections of the beam.

In engineering, beams are of several types:

  1. Simply supported – a beam supported on the ends which are free to rotate and have no moment resistance.
  2. Fixed – a beam supported on both ends and restrained from rotation.
  3. Over hanging – a simple beam extending beyond its support on one end.
  4. Double overhanging – a simple beam with both ends extending beyond its supports on both ends.
  5. Continuous – a beam extending over more than two supports.
  6. Cantilever – a projecting beam fixed only at one end.
  7. Trussed – a beam strengthened by adding a cable or rod to form a truss.
