STATIC AND REPEATED-LOAD STRENGTH OF BOLTED TIMBER JOINTS

A description and the results of an investigation conducted to determine the relative static and repeated-load strength of bolted timber joints as ordinarily used to fasten the sway bracing to the piles or caps in timber pile trestle construction is given. Full-size timbers are included in the investigation. Test machines and test specimens are described. Results of static tests and repeated-load tests are tabulated. For each size of sway brace, each species and whether treated or untreated, the family of curves shown indicates that the repeated-load strength decreases as the number of load cycles increases. Higher repeated-load strengths are obtained with 4 inch sway braces than with 3 inch sway braces using the same size of bolts.
