Types of beam

Types of beam
  • Simply supported beam
  • Cantilever beam
  • Overhanging beam
  • Continuous beam
  • Fixed beam.         
A simply supported beam is a type of beam that has pinned support at one end and roller support at the other end. Depending on the load applied, it undergoes shearing and bending. It is the one of the simplest structural elements in existence. The following image illustrates a simply supported beam.

A cantilever beam is a  anchored at only one end. The beam carries the. load to the support where it is forced against by a moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs.

A overhanging beam, the bending moment is positive between the supports, whereas the bending moment is negative for the overhanging portion. At the same point on the beam, the bending moment is zero or changes sign from positive to negative value or vice versa.


A continuous beam is a statically indeterminate multispan beam on hinged support. The end spans may be cantilever, may be freely supported or fixed supported. At least one of the supports of a continuous beam must be able to develop a reaction along the beam axis.


A fixed beam end moments are reaction moments developed in a beam member under certain load conditions with both ends fixed

Hardy slab and where it use

  HARDY SLAB :- These kind of slabs are generally seen in Dubai and China. This  slab is constructed by hardy Bricks. Hardy bricks are hollow bricks and made up of concrete Hollow blocks are used to fill portions of the slab thickness it saves the  amount of concrete and hence the own weight of the slab is reduced. This kind of slab has a more thickness when compared with the conventional one. The thickness of hardy slab is 0.27m. The method of installing Hardy slab is different from normal  and it is clearly explained below: This is a one of the types of concrete slabs. The dimensions of Hardy brick is 40cm x 20cm x 20cm The process of execution is as follows: Step 1   : Formwork is arranged and then shutters are fixed on the formwork. Step 2  : Hardy blocks are placed on the shutter with one brick gap on the entire shutter. Step 3  : The gaps between the bricks are called as rib. Reinforcement is provided in a form of beam within the ...

Waffle slab and where to use

  WAFFLE SLAB :- Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides. This kind of slab is majorly used at entrance of hotels, Malls, Restaurants for good pictorial view and to install artificial lighting. This a  type of slab where we find hollow hole in the slab when the formwork is removed.  Firstly PVC trays (pods) are placed on shuttering then reinforcement is provided between the pods and steel mesh is provided at top of the pods and then concrete is filled. After concrete sets the formwork is removed and PVC pods are not removed. This forms hollow hole in it in which hole is closed at one end. The concrete waffle slab is often used for industrial and commercial buildings while wood and metal waffle slabs are used in many other construction sites. This is a one of the types of concrete slabs. Where to use? A waffle slab is a type of slab with holes underneath, giving an appearance of waffles. It is usually used where lar...

About slump cone test in concrete

Concrete Slump Test for Workability -Procedure and Results. Concrete slump test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Procedure for Concrete Slump Test: Clean the internal surface of the mould and apply oil. Place the mould on a smooth horizontal non- porous base plate. Fill the mould with the prepared concrete mix in 4 approximately equal layers. Tamp each layer with 25 strokes of the rounded end of the tamping rod in a uniform manner over the cross section of the mould. For the subsequent layers, the tamping should penetrate into the underlying layer. Remove the excess concrete and level the surface with a trowel. Clean away the mortar or water leaked out between the mould and the base plate. Raise the mould from the concrete immediately and slowly in vertical direction. Measure the slump as the difference between the height of the mould and that of height poin...
