With the promotion of the concept of green building, light prefabricated buildings have been vigorously promoted in my country. Social and market demands are increasing year by year, among which light steel structures are widely used.How to optimize the layout of light steel structure keel in XuZhou SAFS steel structure engineering factory? Let’s take a look at the analysis below.
The construction of light-weight steel structure integrated residential buildings led by the keel structure system has developed rapidly and has become an important field for the promotion of green buildings, and there are a large number of engineering cases across the country.
The material saving and material resource utilization index is an evaluation mark for the structural specialty in the design stage. In the world green building evaluation system, material and resource utilization are regarded as an important evaluation index. Therefore, designing a new type of keel structure layout scheme with high structural efficiency is the engineering development demand of light steel structure buildings in terms of building energy conservation, and it is also a key problem to be solved in the development process of green buildings.
Structural optimization
Light steel structure buildings have sufficient space for optimization in the layout of the keel structure. In terms of structural section materials, the optimization goal is to reduce the stress generated by the structure and the amount of material. Under the same horizontal load or vertical load, the keel layout is optimized, and the new truss-type keel is used to replace the conventional vertical keel.
A new type of truss keel structural system is formed, and the product of rod length and stress is used as the structural efficiency to judge. Comparing the structural efficiency of different keel layout schemes, a new type of keel structure layout scheme with better structural mechanical performance and material saving effect is obtained. In the process of green building promotion, give full play to the building energy-saving efficiency of the new truss-type keel structure system adopting this scheme, and achieve the purpose of reducing the consumption of building materials, energy saving, environmental protection and sustainable development.
After a large number of parametric analysis of the model to obtain data, the corresponding data processing is carried out. The concept of “structural efficiency” is introduced, and under the condition of achieving the same structural purpose, the number of structural components is reduced as much as possible, thereby reducing the consumption of building materials and meeting the requirements of green buildings of energy saving and environmental protection. Taking small structural stress and material consumption as the optimization goals, the keel layout scheme of the light steel structure keel structure system under different load conditions and wall height-to-width ratios is calculated and analyzed, and the effect of structural joints is quantified.
