Overview

Randomized trial evaluates the impact of eccentric assembly on fatigue life in high-strength bolts, indicating significant reduction in performance.

Key Points

  • This study aims to investigate how eccentric assembly affects the fatigue life of high-strength bolts under cyclic loading conditions.
  • Developed a load-transfer framework for M16 high-strength bolts considering external load and stress;
  • Combined a statically indeterminate beam model with finite element analysis to evaluate thread-root stress;
  • Conducted calibration and fatigue tests at eccentric assembly angles of 0°, 1°, and 2° under a preload of 120 kN.
  • Fatigue life notably decreased from 72,023 cycles at 0° to 52,010 cycles at 1° and 30,742 cycles at 2°;
  • Simulated bending moments matched strain-gauge measurements;
  • Theoretical thread-root stresses differed from finite element model results by no more than 6%.
