Guides, tutorials and reference documentation for RooFit.
BS 6399 (Withdrawn) – Loading for Buildings
Former British Standard for loading, now superseded by Eurocodes. Historical reference only.
BS 5534 – Slating and Tiling for Pitched Roofs
UK standard for design and installation of slating and tiling. Includes wind load calculations specific to roof coverings and fixing requirements.
BS 5268 (Withdrawn) – Structural Use of Timber
Former British Standard for timber design, superseded by BS EN 1995 (Eurocode 5). Historical reference only.
BS EN 1991-1-3 – Actions on Structures: Snow Loads
Determines snow loads on roofs based on ground snow load, roof geometry, exposure, and thermal properties. Includes shape coefficients for various roof types.
BS EN 1990 – Basis of Structural Design
Establishes principles and requirements for safety, serviceability and durability of structures. Defines partial safety factors and load combinations used throughout structural design.
BS EN 1991-1-1 – Actions on Structures: Densities, Self-weight & Imposed Loads
Specifies densities of construction materials, self-weights, and imposed loads for buildings. Category H covers roofs accessible for maintenance only.
BS EN 1991-1-4 – Actions on Structures: Wind Actions
Provides methodology for determining wind loads on structures including pressure coefficients, terrain roughness, and dynamic effects. Critical for solar PV uplift calculations.
BS EN 1995-1-1 – Design of Timber Structures
Design rules for timber structures including strength classes, member sizing, deflection limits, and connection design. Applies to timber rafters and joists.
BS EN 1993-1-1 – Design of Steel Structures
Design principles for steel structures covering yield strength, buckling, connections, and fabrication. Used for steel purlins and flat roof beams.
