Roof Rafter System Structural Design and Calculation ArchiCAD

Roof Project with Aspen Shingle Covering - Full Structural Design Cycle

A professional structural design of the rafter system was completed with a 32° slope, determined by the architectural logic of the building and the technological requirements of the aspen shingle roofing.

The structure was developed as an integrated spatial system, where each element operates in coordination with the floor structure, wall top binding, and the building’s load-bearing frame, ensuring not only structural strength but also the geometric stability of the entire roof.

The project includes:

– detailed roof plan with actual geometry of slopes, overhangs, and junctions
– architectural and structural sections revealing the structural behavior of the rafter system in volume
– structural nodes developed with real load transfer logic, without abstract or schematic assumptions
– justified selection of rafter, beam, and wall plate cross-sections
– load calculations considering roofing weight, snow load zone, and spatial configuration
– working specification of structural timber elements for construction implementation

Special attention was given to the integration of the roof with the floor structure, including the system designed for light cob (lightweight clay) infill, ensuring full structural compatibility and preventing secondary deformations.

The project was developed in ArchiCAD with precise geometric coordination of all elements, allowing the documentation to be used directly for construction without additional revisions.

This is not a conceptual diagram, but a real construction document reflecting the true structural behavior of the roof system.
