Structural Characteristics
1. Lightweight, reducing construction costs
Compared to traditional reinforced concrete structures, gantry steel structures are significantly lighter. Generally, for buildings without bridge cranes, the steel consumption is usually 20-35kg/㎡; for buildings with bridge cranes, the steel consumption is only 35-50kg/㎡. This reduces the load on the foundation, lowering the foundation cost. Taking a single-story industrial plant as an example, the use of a gantry steel structure reduces the overall building weight by about 40% compared to a reinforced concrete structure of the same size, saving about 25% on foundation costs, effectively reducing the initial construction cost of the project.
 

2. Large span, flexible space utilization
Gantry steel structures can achieve a large span, generally a single span can reach 9-36m, and a multi-span can reach more than 60m. The large span feature makes the interior space open, allowing for flexible division of functional areas according to actual needs, without the need for too many intermediate columns. This is especially suitable for industrial plants, warehouses, exhibition halls, and other buildings with high space requirements. For example, a large logistics warehouse using a gantry steel structure has created a column-free large space, facilitating the free operation of forklifts and other logistics equipment, greatly improving the utilization efficiency of the warehousing space.
 

3. Fast construction speed, shortened construction period
After the components of this structure are prefabricated in the factory, they are transported to the construction site for assembly installation. The components are mostly connected by bolts, the installation process is simple and fast, and no large-scale on-site wet work is required. Compared with traditional building structures, the construction period of gantry steel structure buildings can be shortened by 30%-50%. A commercial exhibition hall project using a gantry steel structure took only 3 months from foundation construction to completion of the main structure, nearly 2 months ahead of schedule, which bought valuable time for the subsequent decoration and operation of the project.
 

4. Superior seismic performance
Steel structures have good ductility and toughness, and can absorb energy through their own deformation under seismic action, reducing the damage of earthquakes to the building structure. Through a reasonable support system and node design, the gantry steel structure further enhances the integrity and stability of the structure, showing strong seismic resistance in earthquake-prone areas. In some earthquake disaster cases, buildings using gantry steel structures have shown significantly less damage compared to buildings of other structural forms, effectively ensuring the safety of lives and property.

 

 

Broad prospects. Currently, the goal of China's construction industry development is to improve the overall quality of the construction industry, the level of industrial production and technological equipment, to achieve strong competitiveness in the international construction market, and to fully utilize the leading role of the construction industry in driving national economic growth and structural adjustment. By 2010, the construction industry will become a truly pillar industry of the national economy. For the construction industry to drive the development of related industries, accelerating the development of steel structure engineering is a very important aspect. Steel structure systems have comprehensive advantages such as light weight, easy installation, short construction cycle, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in the development of "high, large, and light" aspects.

Steel structures have many advantages, including light weight, easy installation, short construction period, good seismic performance, quick return on investment, and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in terms of height, size, and lightness.
