Abstract
To investigate the effect of electro-slag weld defects on fracture of steel box column plate, finite element analysis was conducted to assess the possibdity of fracture of column plate through performance indices, such as crack tip opening displacement (CTOD) , stress triaxiality, and rupture index. The analysis results of the finite element parametric study show that the variables of the backing plate slit and the deviation of the beam flange with respect to the diaphragm have little effect on fracture of box column plate. However, at the slit of backing plate and column plate,a smaller distance from fusion line to the diaphragm due to the eccentricity of the fusion results in a larger CTOD,stress triaxiality, and rupture index which could be detrimental to the column plate and cause the fracture.关键词
