Detailed guidelines to create BBS of a cantilever beam in excel

This civil engineering video tutorial is based on creating bar bending schedule of RCC cantilever beam with the use of excel program.

Cantilever beam stands for a rigid beam or bar that is attached to a support generally a vertical structure or wall and the beam's other end is free. The fixed end of the beam contains a reaction force & moment caused by the load operating at the free end.

Cantilever construction is suitable for overhanging structures exclusive of external bracing. Cantilevers are also built up with trusses or slabs.

Dimension and properties of cantilever beam :-

For structural steel
Length = 1500 mm
Width = 100 mm
Thickness = 10 mm
Height = 200 mm
Young Modules (MPa) = 2 x 105
Density (Kg/m³) = 7850

For Grey Cast Iron
Length = 1500 mm
Width = 100 mm
Thickness = 10 mm
Height = 200 mm
Young Modules (MPa) = 1.1 x 105
Density (Kg/m³) = 7200

For Stainless Steel
Length = 1500 mm
Width = 100 mm
Thickness = 10 mm
Height = 200 mm
Young Modules (MPa) = 1.93 x 105
Density (Kg/m³) = 7750
