Abstract

Abstract

High-strength bolts in prefabricated buildings have become the main connection method due to their convenient construction and excellent mechanical properties. In order to study the influence of pre-tension on the fatigue performance and fatigue failure mechanism of high strength bolts for steel structure， the fatigue test was carried out by MTS Landmark370.50 servo hydraulic fatigue testing machine. The constant amplitude fatigue test data of 25 M24 high strength bolts were obtained， and the fatigue fracture was analyzed by scanning electron microscopy. The results showed that the bolt basically breaks at the bottom of the thread at the bite of the screw and nut under full pre-tension. Compared with the fatigue fracture of high strength bolt without pre-tension， the proportion of the instantaneous fracture area of the fatigue fracture under pre-tension was relatively large， the fatigue source was relatively single， and the dimples in the instantaneous fracture area were dense but relatively small. The fatigue failure mechanism of bolt under pre-tension was revealed， and the fatigue design method of M24 high strength bolt was established.
