INFLUENCE OF CYCLIC LOADING ON THE SLIP FACTOR FOR FRICTION-GRIP JOINTS

The paper is concerned with the influence of cyclic loads on the slip factor for high-strength friction-grip bolted joints. Static and cyclic load tests on specimens with four different surface finishes are described, viz., galvanized, mill scale, urethane chromate primer and an inorganic zinc silicate coating. The first three surfaces mentioned furnished an increase in their associated slip factors, for cyclic loads less than their initial static slip-load values. Three variable programmes of cyclic loading were used; the frequency of loading was 0.6hz. Reference is made to bolt tension losses. /TRRL/
