What are the characteristics of steel structures? Material requirements for steel structures
The material has high strength and light weight. Steel has high strength and high modulus of elasticity. Compared with concrete and wood, the ratio of its density to yield strength is relatively low. Therefore, under the same stress conditions, the steel structure has a small cross-section and light weight, which is convenient for transportation and installation. It is suitable for large spans, high heights, and heavy loads.
