What Is A Beam ? Classification Of Beams

BEAM is a horizontal member which carries load primarily by bending. Meaning its a flexural member.BEAM can resist vertical gravity loads (self-weight, floor loads, live loads) and horizontal loads (lateral forces like wind, earthquake)

BEAM take axial loads- tension taking members are called tie beams and compression are called strut beams.BEAM analysis is done assuming different end- conditions like simply supported, continuous, cantilever, fixed. Analysis using force methods and displacements methods. Recently Finite Element Method has been vital in the analysis using the software.

BEAM design involves assigning shapes and reinforcement (r.c.c). Rectangular or T shaped is most commonly used in R.C.C.I shaped or L shaped ( Angle sections )  or C shaped (channel sections )used in steel

BEAM experiences bending stresses (compressive and tensile in nature) and shear stresses.

BEAM properties like stiffness (elasticity modulus (E) and second moment of area (I)) are very important in calculating deflections. deflections are important in terms of safety and appearance.

Classification of Beams:

Classification of beams is basically based on:-

  1. Classification of beams based on supports
  2. Classification of beams based on geometry
  3. Classification of beams based on the shape of cross section
  4. Classification of beams based on equilibrium conditions
  5. Classification of beams based on material

Beams are classified on the basis of their geometry and the manner in which they are supported.
