The earlier brittle fracture in beam flange has been observed in experiments on beam-to-column connections under cyclic loadings. The fracture mainly occurs at the square corner of weld access hole at which hole surface meets to flange surface. To investigate the phenomenon, a series of tests on beam-to-column connections were carried out with regard to geometrical condition of the access hole and mechanical properties of beam materials. Test results show that shape of the hole and fillet weld of backing strip have an important influence upon the fracture behaviour and that low fracture toughness of the steel only has a bad effect on the fracture when the hole has ill-conditioned geometry. As a result, appropriate geometry of weld access hole to prevent early fracture is proposed.
