Abstract

In the current study, a research was conducted in three different steel categories of high and medium ductility such as B400c, B450c and B500b under seismic loads which were simulated with low cycle fatigue tests. Based on the results of mechanical tests, SEM and EDX on the above steel specimens before and after accelerated corrosion it is important to mention the negative role of sulfides, as it is mainly MnS inclusions, with existence of chloride ions and buckling phenomena in Structural Integrity of rebars.

Keywords: steels; seismic loads; structural integrity.
