Abstract

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.

建筑用钢在拉应力下的磁性变化。亥姆霍兹线圈的实证研究

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。
