Ultimate shear resistance of S600E high-strength stainless steel plate girders
Abstract The S600E high-strength stainless steel (HSSS) is a new type of sorbite stainless steel. Compared with the traditional stainless steel, the S600E HSSS performs the higher yield strength and faster strain hardening property. The numerical analysis for S600E and S30408 stainless steel plate girders was performed, which includes the material and geometrical nonlinearity. The results indicated that differences in the material property would influence the resistant property of plate girders developing postbuckling capacity (PC). After the verification, the design formulae in EN 1993-1-4 + A1 are too conservative to be directly used to predict the ultimate shear resistance of the S600E HSSS plate girder. Hence, the objective of this study is to quantify the ultimate shear resistance and propose the modified formulae for S600E HSSS plate girders with PC. The effects of a/h w, h w/t w and t f on the ultimate shear resistance were investigated through a parametrical study. The results stated that the a/h w has an adverse effect on the ratio c/a, which is not included in the traditional design formula. Based on the numerical outcomes, the factor ρ was introduced. To consider the strain-hardening effect, a strengthen factor δ = 1.2 is recommended in the formula for the contribution from flange. The contribution from the web was investigated by V bw.Rd = V b.Rd - V bf.Rd. Then, the new formula was proposed for the contribution from the web based on the resistant property of S600E HSSS plate girders with PC.
