Abstract: The finite element analysis(FEA)methodology for premium connections subjected to bending load is established with the software of Abaqus, and then used for pure bending property analysis of premium connections with a certain size. The results reveals that along with the increasing of the bending moment, the contact stress, contact length and sealability decrease in the tensile side, whereas all of these values increase in the compression side, which implies that for improving the bending property of the premium connection both the tensile property and compression property thereof should be enhanced, too.
