Hot-rolled ribbed steel bars (commonly known as "rebar") have ribs on the surface (crescent ribs, equal-height ribs, etc.), which can form a firm bite with concrete. The core is used to support the concrete structure and is an indispensable "skeleton material" in construction projects.
Seismic-grade rebar:
1. According to GB standards, seismic-grade rebar with an “E” designation (e.g., HRB400E) must meet yield-to-strength ratio ≤ 0.85, strength-to-yield ratio ≥ 1.25, and elongation ≥ 9% to enhance seismic ductility.
2. The core objective is to control mechanical properties to ensure the rebar is less susceptible to brittle fracture during earthquakes, making it suitable for buildings with high seismic resistance requirements.
