摘要

钢负责为钢筋混凝土结构提供抗挠曲性。钢负责为钢筋混凝土结构提供抗弯强度。因此，研究其在不同拉伸状态下的性能是非常重要的。本研究使用的测量设备能够在标准拉伸试验中确定B500-SD钢筋的磁性能变化。亥姆霍兹线圈产生的磁场通过二次回路收集。这使得感应电动势与经受试验的钢挠曲阶段有关。此外，还可以确定12mm和16mm直径的棒材在不同拉伸状态下的磁导率变化。这种方法在确定嵌入混凝土结构的带肋钢筋的拉伸状态方面非常有用。

Magnetic variation in construction steels under tensile stress. Empirical research with Helmholtz coils

Steel is responsible for providing resistance to flexotraction to reinforced concrete structures. Steel is responsible for providing reinforced concrete structures with a flexural strength. For this reason, it is important to study its behaviour under different tensile states. This study used measuring equipment that was able to determine variations in magnetic properties of B500-SD steel bars during standard tensile tests. The magnetic field generated by a Helmholtz coil was collected through a secondary circuit. This enables the induced electromotive force to relate with the steel deflection stages when subjected to the tests. Moreover, it was possible to determine the variation of magnetic permeability when submitting 12mm and 16mm diameter bars to different tensile states. This method could prove extremely useful in determining the tensile state of ribbed steel bars that are embedded into the concrete structure.

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.
