Introduction
Structural calculations demonstrate that a building structure is capable of safely supporting loads.
For home extensions and structural alterations, these calculations are often required as part of the Building Regulations approval process.
Structural calculations are particularly important where new structural elements such as beams or openings are introduced.
When Are Structural Calculations Required?
Structural calculations may be required for projects involving:
- steel beams (RSJ beams)
- removing load-bearing walls
- large structural openings
- loft conversions
- double storey extensions
They ensure that the structure can safely carry loads from floors, roofs and walls.
Why Structural Calculations Are Important
Structural calculations help ensure:
- structural safety
- compliance with Building Regulations
- correct beam sizing
- proper load distribution
Without proper calculations, structural alterations can compromise the safety of the building.
What Information Is Used?
Structural calculations are typically based on:
- architect drawings
- beam spans
- loads from floors or roofs
- support conditions
These factors allow engineers to determine the appropriate structural design.
Structural Calculations and Building Control
Building Control may request structural calculations when reviewing an extension or structural alteration.
These calculations demonstrate that the structure complies with Building Regulations.
