Popis:	Steel grating is a flooring system used primarily in industrial structures and is commonly supported by I-beams or steel channels. The capacity of the beams is related to their potential to buckle laterally. To prevent premature failure, resulting from buckling, beams are braced using angles, cross-beams or slabs. The interaction between the grating and the support beam will, however, cause a frictional reaction, which will potentially brace the beam laterally and prevent lateral buckling of the compression flange. A series of tests were conducted to determine the coefficient of friction between steel grating and the support beam under various loading and surface conditions. Several tests were also conducted to determine if grating will prevent buckling of a beam, which otherwise would buckle without lateral restraint. The tests suggest that buckling is prevented and therefore grating does provide lateral restraint.
