ActiveStructural section steels with improved seismie resistance
抗震结构用型钢
Application Summary AI generated
GB/T 28414-2012 specifies technical requirements for hot-rolled structural section steels (such as H-beams, I-beams, and channels) with enhanced seismic performance, including controlled yield strength ratios, low carbon equivalent values, and guaranteed impact toughness. It is applied in the construction of steel-framed buildings, bridges, and industrial facilities in earthquake-prone regions, ensuring that structural components can withstand cyclic plastic deformation during seismic events. The standard is used by steel mills for production and by structural engineers for material selection in seismic design.
