Abstract

Abstract

Taking the widening flange section, side-plate reinforced section, flange-plate reinforced section, coverplate reinforced section, reduced beamed section, and ordinary section as research objects, it was made a comparative analysis of the possibility of brittle fracture for six typical rigid joints in steel structure.Establishing the model by non-linear finite element method, with both the plastic equivalent strain index(PI) and rupture index(RI) serving as determinate indicators, it was compared the stress distribution for all kinds of joints and analyzed the rupture parameters between three appointed paths and four critical points.In addition, it was also conducted a comprehensive analysis of the difference in brittle facture characteristics among the six typical rigid joints, and told the key sites where the fractures were easy to occur, based on which, it was to concluded that the capability of avoiding brittle fracture of the flange-plate reinforced joints was superior to the others．
- rigid joints,
- brittle fracture,
- plastic equivalent strain index,
- rupture index
