Volume of beam 10.0 x 0.6 x 0.3 = 1.8 m3
Unit weight of reinforced concrete = 24 kN/m3
Therefore, dead load of beam = volume x unit weight
= 1.8 m3 x 24 kN/m3
= 43.2 kN
Dead load on a structure is the result of the weight of the permanent components such as beams, floor slabs, columns and walls. These components will produce the same constant 'dead' load during the lifespan of the building. Dead loads are exerted in the vertical plane.
Dead load = volume of member x unit weight of materials
By calculating the volume of each member and multiplying by the unit weight of the materials from which it is composed, an accurate dead load can be determined for each component.
The different components can then be added together to determine the dead load for the entire structure.
