Efficient curved form
Curved geometry can mobilise membrane-like and spatial action when supports, openings and load paths are resolved correctly.

ZABALERA · STRUCTURAL SYSTEM
Domes & Vault Structures
Spatial structures for worship, civic, exhibition and specialist architectural projects where the roof geometry itself defines the building. Dome and vault solutions can use space-frame, truss or hybrid structural logic depending on scale, support conditions and envelope.
WHERE IT FITS
Use the structural form where the project logic supports it.
No structural family is automatically the right answer. Geometry, loads, support conditions, architecture, freight and erection all affect system selection.

SYSTEM LOGIC
What this structural pathway can contribute.
Strong architectural identity
A dome or vault can define the internal volume and external silhouette rather than simply covering the building.
Multiple envelope options
Metal, glass and selected membrane or hybrid roof build-ups may be coordinated when their support, movement and waterproofing interfaces are verified.
Modular fabrication
Complex curved forms can be broken into rational repeatable members and nodes for manufacture and erection.
BEFORE SYSTEM SELECTION
Questions that materially change the structure.
01
Diameter / span and rise
02
Support ring and opening geometry
03
Roof / glazing build-up
04
Movement and expansion strategy
05
Drainage and waterproofing
06
Design wind / seismic criteria
07
Temporary works / erection sequence
08
Architectural finish and exposed structure
TECHNICAL CONTROL
Span is an outcome of engineering — not a marketing number.
ZABALERA does not publish a single maximum span as though it applies to every structural family. Final practical span depends on system type, roof geometry, loading, structural depth, supports, service loads, environmental criteria, fabrication, transport and erection constraints.
