Abstract

The main focus of this article is to explain the scientific and engineering principles behind the development of seismic steel, which is specifically engineered to withstand seismic forces during earthquakes. Through careful control of the steelmaking process, including alloy chemistry and thermomechanical treatments, microstructures are created that provide the necessary strength, ductility, and toughness for seismic applications. S700 steel, also known as ultra-high-strength steel (UHSS), is an advanced material that has gained significant interest in recent years due to its exceptional mechanical properties. It is an example of seismic steel. This review aims to provide an overview of S700 steel, including its composition, characteristics, applications, recent advancements in the field, and potential benefits and challenges associated with using this material. The simulations using JMatPro have shown promising findings, concerning the potential for the studied modified S700 steel alloy to enhance structures' safety and resilience in earthquake-prone regions, as well as the combination of S700 steel and JMatPro represents a significant advancement in materials science and engineering.
