The bearing capacity of stiffener members has been greatly improved by paring the calculation results through simulation analysis on axial pressed bearing capacity. Also,by grouping nine entity models basing on their lengths and heights,size range of the stiffener of greater bearing capacity can be obtained.The bearing capacity has been shown to be significantly improved after analyzing both the increment of bearing capacity of the stiffener and the one of steel consumption.
