Abstract
A detailed 3-D fracture mechanics model with a crack near bolt hole is established for a simple-supported steel truss bridge, the crack growing is simulated, and the elastic-plastic parameters near crack tip are studied. The results reveal that the elastic-plastic rigidity index is obviously effected by the crack length along the direction parallel to and perpendicular to cracking line, and the materials near crack tip become more brittle with the crack growing.
