ICC-ES AC532 – Acceptance Criteria for 3D Printed Steel Nodes Used in Space Frames
Scope
ICC-ES AC532 defines the acceptance criteria for evaluating 3D printed steel nodes used in space frame structures. Space frames are lightweight, truss-like structures used for roofs and other architectural applications. The nodes are the connection points where the individual members of the space frame come together.
The scope of AC532 includes:
- Material properties: evaluation of the mechanical properties of the 3D printed steel, including tensile strength, yield strength, elongation, and fatigue resistance, to ensure it meets the required structural performance.
- Manufacturing process: assessment of the 3D printing process and quality control measures to ensure consistency and reliability in the production of the nodes.
- Connection design: evaluation of the design of the nodes, including their geometry, size, and connection details, to ensure adequate load transfer and structural integrity of the space frame.
- Structural analysis: assessment of the structural analysis methods used to determine the load-carrying capacity and behavior of the space frame under various loading conditions.
The evaluation process typically involves a combination of testing, calculations, and review of manufacturer’s documentation to verify compliance with the acceptance criteria.
