Project Challenges
Structural Adaptability
Designing a structure that allows for future expansion by removing secondary structures and interior columns, retaining only the roof trusses.
Load Management
Ensuring the roof truss system can accommodate both current and future loading scenarios, including a maximum deflection of 4.5 inches under snow load, in compliance with regional standards.
Panel Attachment Integrity
Implementing a panel attachment system that maintains stability during structural shifts and accommodates thermal expansion, preserving airtightness and moisture control.
Custom Norbec Solution
To meet the project’s structural and performance requirements, Norbec provided a tailored solution, incorporating Norex-L insulated metal panels.
Bridging Columns with Sliding clip
Sliding clip were added roof truss to accommodate future expansion and differential movement, ensuring structural flexibility while controlling load transfer.
Norbec’s standard 1-inch attachment system was securely fastened to the secondary structure with high-strength screws, ensuring stability and compliance with deformation
tolerances.
Structural Performance Under load
Deformation Under Load
The roof truss system was designed to accommodate natural deflection under dead load. A maximum deformation of 4.5 inches under snow load was accounted for, ensuring compliance with regional standards.
Adaptation for Wind Load Performance
Due to technical constraints, bending a thicker sliding clip was not feasible. Norbec supplied thinner 11-gauge plates, which were doubled during installation to ensure adequate structural reinforcement.
The system achieved non-factered wind load resistance of 19.3 PSF at wall corners and 17.7 PSF on walls for a low-rise building.

RESULT
Columns with sliding clip
Integration of sliding brackets to allow future expansion without adding columns. This solution reduces structural stress by accommodating differential movement between components.
Norbec panel fastening
The panel system was engineered to tolerate up to 1 inch of deformation. Panels were securely fastened to the secondary structure using screws, ensuring long-term stability and compliance with movement tolerances.
