The design of a steel structure space frame is a complicated project, which needs to pay attention to the following points:

1. Structural form and node design: the structural form and node design of the steel structure space frame is the key, which needs to fully consider the force situation, stability, safety, and construction feasibility of the structure. The node design should meet the requirements of force transmission and structure, and at the same time, consider the construction convenience and economic rationality.

2. Material selection and cross-section form: According to the span, load, and span requirements of the space frame, reasonably select the grade and specification of steel, and determine the appropriate cross-section form. Different cross-section forms have different stress characteristics and applicable ranges and should be selected in combination with the actual situation.

3. Estimation and calculation: In the preliminary design stage, the span, height, and node form of the frame should be estimated and calculated according to the experience, and the general structural form and size should be determined. At the same time, the self-weight of the structure, use load, seismic action, etc. should be considered to ensure the safety and stability of the structure.

4. Drawing and deepening design: According to the estimation and calculation results, carry out detailed drawing and deepening design, including node sample drawings, detailed drawings of components, installation node drawings, and so on. The drawing should be clear, accurate, complete labeling, and convenient for construction, installation, and acceptance.

5. Review and optimization: After completing the preliminary design and deepening design, review and optimization should be carried out. Detailed analysis and calculation of the structure should be carried out to ensure the safety and stability of the structure. At the same time, the operability, economy, and environmental protection of construction should be considered to optimize the design.

4. Fabrication and installation: The fabrication and installation of the steel structure space frame need a professional construction team to complete. A qualified and experienced construction team should be selected to fabricate and install according to the design drawings and construction specifications. Attention should be paid to quality monitoring and safety management during construction to ensure project quality and personnel safety.

In conclusion, the design of a steel structure space frame needs to pay attention to the structural form and node design, material selection and section form, prediction and calculation, drawing and deepening design, review, and optimization, as well as production and installation. It is necessary to comprehensively consider the stress situation, stability, safety, and construction feasibility of the structure to ensure the safety and stability of the structure. It is also necessary to pay attention to such issues as economy and environmental protection, optimize the design, and improve the economic and social benefits of the project.
