A structural grid is a regular grid of lines that orders the load-bearing structure (the columns and walls) of a building. It sets out the grid dimension and provides a consistent framework that makes modular, coordinated construction possible.
Characteristics
- Regular spacing — lines run at fixed centres in two directions
- Grid dimension — the chosen module governs the spacing of columns and walls
- Coordination — components, cladding and services align with the grid
- Efficiency — repeated bays simplify design, fabrication and assembly
Application
How it is used
- Setting out the structure — columns are placed at grid intersections
- Modular construction — a repeated module allows prefabricated, interchangeable parts
- Space planning — the grid guides the layout of partitions and services
Types of grid
- Rectangular grid — the most common, with bays in two directions
- Diagrid — a diagonal grid used for some tall or curved structures
- Spacing is described by the centre-to-centre distance between lines
