EFFECT OF SURFACE COATINGS AND EXPOSURE ON SLIP

EIGHTEEN JOINTS OF A36 STEEL WERE TESTED TO INVESTIGATE THE EFFECTS OF SURFACE COATINGS ON SLIP BEHAVIOR. ALL SPECIMENS WERE DOUBLE LAP BUTT SPLICES WITH A325 HIGH-STRENGTH BOLTS AND WERE INITIALLY BLAST CLEANED. THREE JOINTS HAD SLOTTED HOLES. THREE WERE EXPOSED 2, 6, AND 12 MONTHS WITHOUT PROTECTIVE COATINGS. NINE WERE TREATED WITH VINYL WASH AND LINSEED OIL AND EXPOSED TO AN INDIVIDUAL ENVIRONMENT FOR TWO MONTHS BEFORE TESTING. THREE WERE TREATED WITH VINYL WASH COATING WITHOUT EXPOSURE. THE SLOTTED HOLES AND THE EXPOSURE WITHOUT PROTECTION REDUCED THE SLIP COEFFICIENT. THERE WAS NO SIGNIFICANT EFFECT IN THE SLIP RESISTANCE WITH OR WITHOUT TWO MONTHS EXPOSURE TO INDUSTRIAL ENVIRONMENT. /ASCE/
