The "Gerber Crack" represents a failure of the expansion joint mechanism rather than a failure of the beam material itself. Immediate intervention via stop-hole drilling and temporary shoring will mitigate the immediate risk. However, a permanent solution requires the restoration of the hinge’s rotational freedom or a redesign of the connection to handle the induced moments.

Not a physical crack, but a Gerber crack : a data-level fracture where the CAD-to-CAM translation had dropped a single line of G-code. gerber crack
