Types of Concrete Beam and their Reinforcement Details

Beam stands for a structural member that provides supports to bear the transverse load that generally builds on the supports at its end. Girder is the part and parcel of a beam that provides strong supports to one or more smaller beam.

Beams are categorized as simple beam, continuous beam and semi-continuous beam.
Simple Beam: This type of beam contains a single span that provides supports at its end devoid of any restraint at the support. Simple beam is also known as simply supported beam. Restraint signifies an inflexible connection or anchorage at the support.

Continuous Beam: This type of beam depends on in excess of two supports.
Semi-Continuous Beam: This type of beam consists of two spans with or without restraint at the two remote ends.

Cantilever Beam: This type of beam is rested on one end and the other end highlights ‘beyond the support or wall.

T – Beam: If floor slabs and beams are poured all together for developing a monolithic structure where the part of the slab at both sides of the beam functions as flanges of the T-Beam. The beam that is situated underneath the slab performs as the web member and is often entitled as stem.

Beam: Introduction, Types and Detailing in Detail

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 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. 

Beams are characterized by their manner of support, profile (shape of cross-section), length, and their material. Beams are traditionally descriptions of building or civil engineering structural elements, but any structures such as automotive automobile frames, aircraft components, machine frames, and other mechanical or structural systems contain beam structures that are designed to carry lateral loads are analyzed in a similar fashion.

Types of Beam Based on shape: 
  • T Beam 
  • L Beam 
Based on support condition 
  • Fixed beam 
  • Simply supported beam 
  • Continuous beam 
  • Cantilever beam 
Based on reinforcement 
  • Singly reinforced beam 
  • Longitudinal Reinforcement is provided in the tension zone only. 
It resists tensile stresses due bending and shear in beams.
