q460d-carbon-steel-h-beam refers to steel with a yield strength of 460 MPa or greater. Applying high-strength steel in structures can reduce the size of the components and the quantity of steel required, thereby decreasing the structural weight and seismic hazard. Some work has been carried out to prove quality control and strength of steel have a major impact on the seismic performance of steel space structures
