Abstract:Taking the welded hollow spherical nodes(D800×32)in Beijing AMECO A380 hangar as studying object, the ultimate bearing capacity of these welded hollow spherical nodes was analyzed subjected to axial compression. First, the ultimate bearing capacity of these welded hollow spherical nodes by FEM method were analyzed, then model experiments were carried out to check the results. The FEM and experiment results indicate that the welded hollow spherical nodes have good behaviors, and the ultimate bearing capacity can meet the demand of designers.
Keywords:welded hollow spherical node; ultimate bearing capacity; full size experiment; FEM analysis
