What is used to express the plastic properties of steel structures

The plastic property of steel structures is mainly expressed by elongation ‌.
Youdaoplaceholder0 elongation ‌ : It is an important indicator of the property that steel can withstand deformation before being damaged by force. Specifically, it is the ability of steel to withstand deformation when it breaks, calculated by the percentage of the increment of the gauge length after the specimen breaks to the original gauge length. This indicator directly reflects the plastic deformation capacity of steel.
Youdaoplaceholder0 cold bending performance ‌ : It is another indicator reflecting the plasticity of steel, and is usually used to assess the plasticity and processing performance of reinforcing bars.
In conclusion, the plastic properties of steel structures are mainly expressed through elongation and cold bending performance, among which elongation is the primary indicator. These indicators are of great significance in engineering applications, as they can assist engineers in evaluating the deformation capacity and processing performance of steel, thereby enhancing the performance and stability of the structure ‌.
