Notes
  1. Load is carried by the grating load bars immediate under wheel + four additional load bars adjacent to wheel.
  2. Allowable span is based on a 0.25” maximum deflection and a Factor of Safety 3.0. The other criteria may be required by certain construction codes. Check codes requirements to determine design criteria.
  3. ALLOWABLE SPAN IS STRONGLY DEPENDENT ON WHEEL WIDTH AND VEHICLE WEIGHT/ LOAD CAPACITY. If your application varies from the values given on this table, contact Fibergrate Engineering for application assistance.
  4. Load based on the AADHTO Standard Truck Load as defined in AASHTO LAFD Bridge Design Specifications. 2nd Ed, This does not imply that the allowable span the deflection requirements of this specification.

Load and Deflection Data N/A N/A Load capacity and deflection data was developed using the Recommended Test Procedures for Access Floors by the Ceilings & Interior Systems Construction Association (CISCA). Setup requires that panels “…shall be supported on an understructure support identical to that utilized in an installed system”.

All Load Points 1" Aquare

Conditions:
CASE I. Concentrated loading at the center of the panel (centroid)
CASE II. Concentrated loading at the mid point of the edge (centerline edge)
CASE III. Ultimate Capacity - Concentrated loading at the center of the panel (centroid)
CASE IV. Ultimate Capacity - Concentrated loading at the midpoint of the edge (centerline edge)
CASE V. Ultimate Capacity - Concentrated loading at the “weakest point” of the panel
CASE VI. Ultimate Capacity - Pedestal
