Classification Criteria for Stainless Steel H-Sections Under Cyclic Loading

School of Civil Engineering, Southeast University, Nanjing 211100, China

摘要

摘要: 为了研究循环荷载下不锈钢H形截面分类，针对奥氏体和双相型不锈钢受弯构件和压弯构件，借助ABAQUS软件建立有限元模型，基于已有试验结果验证了有限元模型的合理性。随后开展大量的参数分析，对欧洲不锈钢规范EN 1993-1-4、GB 50017—2017《钢结构设计标准》和CECS 410∶2015《不锈钢结构技术规程》关于H形截面分类限值的适用性进行评估。结果表明，由于没有考虑翼缘和腹板之间的相互约束作用及在循环荷载下材料强化的影响，现行规范的截面分类结果偏于保守。最后，提出了针对循环荷载下不锈钢H形截面分类的建议方法。

Abstract: To investigate the classification of stainless steel H-sections under cyclic loading， this study established models for austenitic and duplex stainless steel beams and beam-columns using ABAQUS finite element software， which verified the reasonableness of the finite element models based on the test results. Subsequently， an extensive parametric analysis was carried out to evaluate the applicability of the European stainless steel design code EN 1993-1-4， the Standard for Design of Steel Structures （GB 50017-2017）， and the Technical Specification for Stainless Steel Structures （CECS 410∶2015） with regard to the limits for the classification of H-sections. The results indicated that the current code results are conservative because they do not consider the effects of interaction constraints between the flange and web or material strengthening under cyclic loading. Finally， a methodology for classification of stainless steel H-sections under cyclic loading was proposed.
