Abstract

The aim of the present study is to develop closed-form formulations for predicting the ultimate compressive and tensional strength of stiffened steel panels with crack damages. First, a numerical database is generated. This database includes the ultimate strength levels of stiffened steel panels with cracks subjected to axial compressive or tensile loads. It was carried out with a series of nonlinear FEM analyses by varying the size of crack damage. In the following sections, regression analysis is used for deriving the empirical formulations. The results of the present paper can be used for the reliability and risk assessment of structures, including stiffened steel panels with cracks.

带裂纹损伤的平面内压缩或拉伸加筋板的极限强度公式

本研究的目的是开发用于预测具有裂纹损伤的加筋钢板的极限抗压和抗拉强度的闭合公式。首先，生成一个数字数据库。该数据库包括在轴向压缩或拉伸载荷作用下具有裂纹的加筋钢板的极限强度水平。通过改变裂纹损伤的大小，进行了一系列非线性有限元分析。在以下各节中，回归分析用于推导经验公式。本文的结果可用于结构的可靠性和风险评估，包括带裂纹的加筋钢板。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
