Roof Design

The bow roof is a structural and architectural element characterized by its curved profile, typically used in wide-span constructions like hangars, warehouses, and agricultural buildings. This report outlines a curvature study based on bow roof prediction calculations and proposes appropriate manufacturing techniques for its fabrication.

Manufacturing a bow roof involves processes that can accommodate complex curves with minimal deformation and high precision.

Material Selection

Steel (cold-formed or hot-rolled sections)

Laminated Timber (Glulam)

Aluminum or composite panels (for lightweight solutions)

Fabrication Techniques

Cold Roll Forming

Suitable for steel profiles.

Continuous bending of a long strip of sheet metal through rollers.

Allows mass production of curved roof purlins and cladding.

Laminated Bending

Used for timber.

Thin wood layers glued and clamped into a curved mold.

Provides strength and flexibility for large spans.

CNC Bending and Laser Cutting

Ideal for high precision in metal components.

CNC-controlled machinery allows tight tolerance and consistent results.

Precast or Prefabricated Panels

For composite or modular bow roofs.

Manufactured off-site and assembled on-site.

Reduces construction time and improves quality control.

Quality Control Measures

Templates and jigs used to ensure accurate curvature during production.

3D scanning or digital twin models verify alignment with design.

Load testing performed on structural samples.
