Abstract
This paper take a bolt-ball node network frame factory building collapse in shanxi as the research background,it suddenly had a partial collapse after used 13 years. Based on the field testing,fracture analysis and theoretical calculation with the finite element analysis software ABAQUS and MIDAS,including the simulating of the M33 high streng bolt’s stress concentration factor and the analysis of the grid structure’s force conditions, we found the cause of the high strength bolt’s fatigue fracture ,and finally,we concluded that this was a rare low cycle fatigue destruction under the action of indirect dynamic load.
