Steel structure building is a building structure constructed primarily from steel, following standardized processes and specifications during design, manufacturing, prefabrication, and installation. The advantages of steel structure buildings are light weight, high strength, good stability, and short construction period. For earthquake prone areas, the seismic performance of steel structure buildings in Xining is superior, thus having good application prospects.
1、 Superior seismic performance of steel structure buildings
Due to the light weight and high strength of steel structure buildings, their structures can have better seismic performance compared to traditional concrete buildings. Specifically, it includes:
1. Steel structure buildings have higher strength and stiffness than traditional buildings, and can better withstand earthquake loads.
2. Steel is a very good plastic material, that is, when subjected to external forces, it can deform well without damage, thereby absorbing energy. Therefore, when constructing steel structure buildings, seismic support can be used to cushion vibrations during earthquakes, thereby reducing the destructive effect of seismic forces.
3. In steel structure buildings, contour steel is usually used instead of reinforced concrete. Under seismic loads, the hysteresis curve generated by the longitudinal displacement of steel structure buildings has a smaller error compared to the expected hysteresis curve, and its hysteresis curve shape is also relatively regular, making it easier to establish accurate mechanical models.
2、 Short construction cycle and high efficiency of steel structure buildings
The construction of steel structure buildings is faster than traditional concrete buildings, which can greatly shorten the construction period. The construction cycle of traditional concrete buildings usually takes several months or more, while steel structure buildings can be completed in just a few weeks to several months. This not only reduces market risk, but also reduces construction costs and improves efficiency.
Compared to traditional buildings, the waist beams, columns, beams, and foundations of steel structure buildings can be factory made, pre installed, or installed on-site by machines, requiring only a small amount of manual operation for on-site assembly, thereby improving production efficiency and reducing construction costs.
During the transportation and installation process of steel structure buildings, each component is standardized and can be manufactured on a large scale according to computer-controlled production methods on the production line, greatly improving manufacturing efficiency, while also improving quality and ensuring accurate delivery deadlines. The fixed components of the entire prefabricated steel structure building can be prefabricated in the factory and then transported to the site for installation, significantly improving the installation speed and progress.
3、 Steel structure buildings for environmental protection and energy conservation
Steel structure buildings are environmentally friendly and energy-saving building forms. With the gradual penetration of the concept of energy conservation and environmental protection, steel structure buildings have evolved into a form of construction that is not only economical but also capable of reducing energy consumption, environmental pollution, using green materials, and being reusable. During the manufacturing process of steel structure buildings, materials such as contour steel and thin steel plates do not cause pollution to the environment and have the characteristic of being reusable.
