Abstract:In order to reduce weakening effect of flexural and tensile loading capacity of aluminum alloy gusset joints caused by cut-outs on the flange and increase design stress ratio, studies were conducted on angle aluminum reinforcing design method of aluminum alloy gusset joints and its influence on capacity, rigidity and bearing mechanism of the joints. The angle aluminum reinforcing design method was used in the reinforcing design of two kinds of typical full-scale aluminum alloy gusset joints in one project in Shanghai. Finite element model was established in ABAQUS and numerical calculation of mechanical property of the reinforced joints under flexural and tensile load was conducted which verified the effectiveness and applicability of the angle aluminum reinforcing design method. Parameter analysis of angle aluminum reinforcing member showed the key parameter which could be used as the basis of optimal design.

Keywords:aluminum alloy gusset joint; failure mode; angle aluminum reinforcing method; effectiveness; parameter analysis
