对受弯剪相互作用的纵向加劲板梁的抗力进行研究。根据一个经过验证的数值模型进行更广泛的数值参数研究。共对630根梁进行分析并将试验结果用于抗力模型的可靠性分析。参考5种不同的抗力模型并确定相应的部分安全系数。抗力模型包括EN1993-1-5中所提到的弯剪(M-V)相互作用抗力模型、改进的M-V相互作用模型、总截面弯曲抗力模型以及两种由前3种抗力模型组合而成的抗力模型。M-V相互作用的研究可以使用部分安全系数1.1的EN1993-1-5中的M-V相互作用抗力模型或部分安全系数为1.1的全截面抗弯强度。
The resistance of longitudinal stiffened plate beams subjected to bending shear interaction is studied. A more extensive numerical study is based on a validated numerical model. A total of 630 beams were analyzed and the test results were used in the reliability analysis of the resistance model. Refer to 5 different resistance models and determine the corresponding partial safety factor. The resistance model includes the bending resistance (MV) interaction model mentioned in EN1993-1-5, the modified MV interaction model, the total cross-section bending resistance model and the two resistance models combined by the first three resistance models . M-V interaction studies may use the M-V interaction resistance model of EN 1993-1-5 with a partial safety factor of 1.1 or the full-section bending strength with a partial safety factor of 1.1.
