Structure & load path
Member stability, gussets, connections and load combinations are assessed as one structural system.
Engineered products
EZdome
Aluminium geodesic dome roof
A lightweight aluminium dome engineered as part of the complete tank: structure, panel system, supports, watertightness, access and installation are considered together rather than as isolated components.
Design intent
The dome is light. The engineering cannot be.
An aluminium dome carries relatively little dead load compared with the environmental load cases it may be required to resist. Structural assumptions, member stability, gussets, fasteners and tank support reactions therefore matter long before a problem becomes visible in service.
EZdome is developed around the complete load path and the complete operating interface: panels and gaskets, tank supports, water tightness, walkways, platforms, constructability and future access are part of the same design decision.
In practice
Project photography
Selected archive photographs from earlier engineering and brochure material. They illustrate proven design principles; current EZdome configurations are engineered to the project and may differ in detail.
Engineering priorities
What the design has to get right.
Watertight envelope
Panel shaping, restraint, gasket compression and joint detailing are treated as a long-term water-management problem.
Tank interaction
Support philosophy and tank-shell reactions are coordinated with the existing or new tank structure.
Build & operate
Erection sequence, access, walkways, platforms and maintainability are considered during design, not after it.
Scope
Typical engineering scope
- Structural analysis against the project load cases and selected design standard
- Strut, gusset, fastener and stability verification
- Panel, batten and gasket / sealing-detail engineering
- Fixed or sliding support interface and tank-load coordination
- Walkways, platforms, handrails and access arrangements
- Manufacturing QA/QC, dimensional control and erection planning
Inputs
What drives the design
- Tank diameter, shell geometry and top-angle / compression-ring details
- Wind, snow, seismic and other governing site loads
- Existing-tank capacity for support reactions and local loads
- Required vents, nozzles, walkways, platforms and instrumentation
- Environmental exposure, drainage and water-tightness requirements
- Installation method, crane access, hot-work limitations and outage window
Standards & project basis
Designed from the application, then checked against the code.
The final code basis is project-specific. EZdome engineering can be developed against applicable tank and aluminium structural requirements, including API 650 and relevant EN / Eurocode requirements where specified.
