PROBLEMS OF HIGH STRENGTH BOLTED CONNECTIONS IN STEEL CONSTRUCTION. COEFFICIENTS OF FRICTION OF FAYING SURFACES SUBJECTED TO VARIOUS CORROSION-PROTECTIVE TREATMENTS

In slip-proof connections of structural steel-members by means of high-strength pre-tensioned bolts, the transfer of forces by friction depends on the manner of pre-treatment of the faying surfaces. It may be expected that the use of corrosion-protective coatings on these faying surfaces, the desirability of which is known from experience, will have a considerable effect on the value of the coefficient of friction, while the manner of the first pre-treatment (before the application of the protective coating) will be less decisive in such cases. This Report No. 2 describes the tests carried out to determine this effect in the context of the objectives of question D 90, and presents the results obtained in these tests.
