Steel structure engineering design is flexible, difficult, large span, and special shapes are all designed with steel structure. As the weight is reduced, the soil quality required for infrastructure construction is less, and the damage to precious land resources is less. The life of the building has expired, the solid waste generated by the demolition of the building is small, and the cost of recycling and utilization of scrap steel is high.
The calculation structure is accurate. Because of the uniform material of steel structure engineering, the strength of steel is uniform, which is inferior to other materials. After the toughness of the steel structure is adjusted with appropriate ingredients and heat treated, its strength and toughness are improved, and the safety is also improved. The use of concrete and bricks has been greatly reduced, and the excavation of rocks around the city has been reduced, which is conducive to environmental protection.
The high degree of industrialization and fast construction speed are conducive to the realization of industrialized production; it has the characteristics of non-combustible, non-combustible, and good fire resistance. The steel structure occupies a small space, which actually increases the use area and improves the use value and economic benefits of the building. Prefabricated steel structural components can be manufactured in the factory, with large output, reduced labor, fast construction speed, short construction period, easy quality assurance, and higher prefabrication accuracy.
The large-span steel structure has better advantages in terms of beam depth and span between columns. For example, the span-to-depth ratio of ordinary reinforced concrete beams is about 1:12, while the span-to-depth ratio of steel structure beams is 1:24.
Beauty and beauty. The auxiliary materials used, such as color panels, aluminum alloys, glass curtain walls, and many other modern products with changeable colors, can be matched with each other to create a beautiful and generous building.
Light weight Generally speaking, the ratio of the weight of the steel structure to the weight of the reinforced concrete is about 1:1.6, and the seismic force = mass * seismic acceleration, so the lighter the weight, the smaller the seismic force. If handled properly, the seismic performance of steel structures will be better.
The use of steel structure engineering can provide larger space and wider construction work surface for construction, and the construction speed is faster. In addition, there are many holes and cavities in the steel structure space, and the webs of the steel beams allow pipes of a certain diameter to pass through, which is also convenient for the arrangement of various pipes. The steel structure is compared with the currently generally used concrete: First, it can be dry-constructed, saving water, hoisting in place, labor-saving, civilized construction, less land occupation, low noise, and less dust; especially in the city center or densely populated areas , Has many advantages.
