What are the basic requirements of steel structure engineering design

1. Steel structure design must meet the needs of socialist modernization construction, implement technical and economic policies of various countries, rationally select materials and structural programs according to the actual situation, so that the structural program can meet the requirements of sustainable development, achieve advanced technology, economic and reasonable, safe application, and ensure quality.

2. Steel structure design should follow the following principles:

(1) The design of building steel structure should first meet the requirements of production process, building function and form, and on this basis to achieve a reasonable, safe, reliable and economic structure. To this end, the structural designer should fully understand the production operation process, building function and artistic requirements, in order to work with the craft and construction personnel to agree on the most reasonable plan.

(2) In the design of steel structure, material supply and construction conditions should be considered, and reasonable selection of materials, structural schemes and construction measures should be taken to meet the requirements of strength, stability and stiffness of the structure in the process of transportation, installation and use, as well as fire prevention standards, and pay attention to the anti-corrosion requirements of the structure. In terms of technical and economic indicators, we should compare multiple schemes, and grasp the main contradiction according to the specific situation through analysis, so as to form a comprehensive economic indicator scheme, so as to save materials, improve production productivity, reduce transportation costs, reduce installation workload and shorten the construction period.

(3) Follow the principle of partial obedience to the whole, should start from improving the comprehensive economic benefits, should not focus on the gains and losses of a component, such as:

1. Unified consideration of superstructure and foundation construction costs;

2. The end height of the roof frame of the workshop and the cost of the wall structure should be considered uniformly;

3 crane workshop column section height is appropriate, the factory building area unified consideration.

4. Focus on the present and the long term. As technology advances and process innovations accelerate, the possibility and simplicity of future retrofits need to be considered in the design.

5. Where possible, move towards structural finalization and standardization of components and connectors. In the specific design, the types of components and connections should be minimized, and the coordination of component parts and the unity of structural treatment should be paid attention to.

6. Follow the principle of centralized use of materials, that is to say, the appropriate extension of the column distance makes the load-bearing structure large-scale, reduce the number of components, steel structure centralized use 1000 to bear the main load, so as to reduce the consumption of steel to bear other loads and special loads (such as earthquake).

7. On the premise of ensuring the safety and reliability of the structure, the principle of functional combination should be implemented, that is, one component can undertake various functions at the same time, such as the structure with both bearing and maintenance functions or the bearing component and the grid framework with stable system.

8. In the selection of steel, the working conditions of the structure, as well as material supply, processing and production, should be considered. Should give full play to the role of all levels of steel, the focus is to promote the use of high efficiency steel.
