为适应国内外建筑钢结构行业的迅猛发展，满足钢结构对建筑用钢板力学性能和特殊性能的要求，首钢自主研发了460 MPa抗震耐腐蚀耐火钢，钢板的屈服强度为460 MPa （简称460FRW钢）。以首钢研发的不同规格的460FRW试制钢板为样本试件，对其进行拉伸和冲击试验，并对试验数据进行统计分析，为首钢生产的460FRW抗震耐蚀耐火钢用于工程设计时提供设计强度建议值。试验采用的460FRW钢板由首钢提供，厚度规格分别为10，14，20，28 mm。根据钢板的强度级别和试件截面尺寸，使试件的屈服荷载位于试验机名义拉力的30%~60%之间，处于试验机柔度影响的合理范围以内。试验机由计算机自动控制，能自动判别并输出上、下屈服强度和抗拉强度，以便进行材料不确定性分析。通过试验，得到460FRW钢的屈服强度的试验数据。根据试验数据，进一步计算钢板的材料性能不确定性统计参数、几何特性不确定性统计参数、计算模式不确定性统计参数，综合此三种不确定性统计参数，计算得到460FRW钢的抗力不确定性统计参数。结合荷载不确定性统计参数，计算得到460FRW钢典型构件轴拉、轴压、偏压（弯矩作用在平面内、外）和型钢梁（弹性和塑性破坏）在四种荷载比ρ下的抗力分项系数。分析可知：当荷载比ρ=2.00时，型钢梁弹性破坏的抗力分项系数最高，以此作为460FRW钢抗力分项系数的统计分析值。
In order to adapt to the rapid domestic and overseas development of structural steel and to meet the requirements of steel structure on the mechanical properties and special properties of steel plate for construction, Shougang has independently developed 460 MPa antiseismic and anti-corrosion fire-resistant steel(hereafter referred to as 460FRW). In this paper, the 460FRW steel plates of different specifications developed by Shougang are taken as samples for tensile and impact tests. The experimental data are statistically analyzed to research on the yield strength,the partial coefficient of resistance and the design strength value of 460FRW steel, so as to provide the recommended design strength value for the 460FRW anti-seismic and anti-corrosion fire-resistant steel produced by Shougang in engineering design. The 460 FRW steel plate used in the test is provided by Shougang, and the thickness specifications are 10, 14, 20, 28 mm, respectively. According to the strength grade of the steel plate and the section size of the specimen, the yield load of the specimen is between 30% and 60% of the nominal tensile force of the testing machine, which is within the reasonable range of the influence of the flexibility of the testing machine. The testing machine is automatically controlled by computer, which can automatically identify and output the upper and lower yield strength and tensile strength for material uncertainty analysis. The experimental data of yield strength of 460FRW steel are obtained by experiments. Based on the test data, the uncertain statistical parameters of material properties, geometric characteristics and calculation mode of steel plate are further calculated and determined. By synthesizing these three uncertain statistical parameters, the resistance uncertain statistical parameters of 460FRW steel are calculated. Combined with the statistical parameters of load uncertainty, the resistance partial coefficients of 460FRW steel typical members under four load ratios, axial tension, axial compression, eccentric compression (bending moment acting in plane), eccentric compression (bending moment acting out of plane) and steel beam (elastic and plastic failure) are calculated. Through the analysis, when the load ratio ρ = 2. 00, the partial coefficient of elastic failure resistance of steel beam is the highest, which can be used as the statistical analysis value of partial coefficient of resistance of 460FRW steel.
