摘要
阐述了波形钢腹板梁的疲劳特性有别于其静力特性,同时波形钢腹板梁具有与平直腹板梁不同的疲劳破坏模式的构造特点,并对疲劳强度的薄弱点进行了评述。系统地介绍了国外对波形钢腹板钢梁和组合梁疲劳特性研究的发展历史和现状,综述了波形钢腹板梁疲劳特性的一些共同性的研究课题,重点包括基于S-N曲线和断裂力学的疲劳寿命评估等,对较为典型的相关研究结果进行了比较。最后,对波形钢腹板梁的疲劳特性开展进一步的相关应用性研究工作提出了建议。
Corrugated web girders possess different behaviors when subjected to fatigue and static loadings.The fatigue failure modes of the corrugated web girders are different from those of the flat web girders.The structural details related to possible fatigue failure were reviewed.The recent research progress regarding the fatigue behavior of corrugated web girders and composite girders was summarized.The fatigue behavior of corrugated web girders were reviewed with special emphasis on the topics of common interest,including the fatigue life assessment based on the mean S-N curves and fracture mechanics theory.Also,the typical research results were studied and compared.Finally,the suggestions for further investigation on the fatigue behavior of corrugated web girders were presented.
