What Affects Deflection
Deflection depends on pane dimensions, glass thickness, support condition, load magnitude, glass build-up, and laminated glass assumptions.
SLS Review
Serviceability checks are normally reviewed separately from ULS stress checks because a pane can be strong enough but still too flexible for the project brief.
Support Conditions
Four-edge, two-edge, and one-edge support conditions can produce very different deflected shapes and governing spans.
Using VitraLab
Enter the pane size, build-up, support condition, and load values, then review the SLS deflection output and utilization ratio.
