LOAD TABLE DATA
  • U = Safe superimposed uniformly distributed load in kilopascals.
  • D = Deflection in millimeters.
  • Mass calculated with grating in an untreated condition.
  • Loads calculated in accordance with an allowable bending stress 171.6 MPa (0.66 Fy).
  • Loads bars are assumed simply supportec and unserrated steel with Fy = 260 MPa.
