Application
• Fastening of cable trays, pipes on a horizontal, braced cantilever support,
fastened on a vertical structure
• Support is fastened by three / six X-ST-GR on both support and brace
baseplate with distance x
• L1 is the distance of the load center to the vertical structure surface, the angle
of the brace is 45°
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of X-ST-GR threaded stud.
Structural analysis of support / structure is NOT in Hilti scope. See the detailed
statements in disclaimer — 2018/05/04
• Shear load fully carried by one / two top X-ST-GR (worst-case)
• Load F acting at the distance of L1 from structure surface
NOTE: load capacity used for calculation N
rec
= 405 lb (axial) / V
rec
= 405 lb (shear)
Technical assessment — maximum of F (depending on load F or lever arm length L1 and baseplate distance x)
