How to design a lintel beam?

Designing a lintel beam requires the consideration of several factors, including the material being used, the size and shape of the opening, any loads that will be placed on the beam, and the spacing between the supports. Once these considerations have been made, it is important to select the appropriate type and size of lintel beam to ensure that it can support the loads safely and prevent buckling or failure.

This should include selecting lintels with appropriate compressive strength, bending moment capacity and shear capacity for their intended application. Additionally, it is important to determine the exact locations of the supports, based on the size of the opening and the amount and type of load being placed on the lintel beam.
