Design factors that must be considered for space frame structure

In the design of space frame structure, there are many factors that must be considered, not only the mechanical properties of the structure, but also many aspects such as society, environment, technology, etc. Generally, the factors that must be considered in the design of space frame structure mainly include the requirements of the owner, the function of the building, Cost, construction, structure, etc.

Mechanical performance requirements are the core content of space frame structure design, and owner requirements, building functions, cost, construction, structure and other aspects are also indispensable and important content of space frame structure design. On the one hand, these factors themselves are factors that must be considered in the structural design. For example, the structure must meet the requirements of the owner, can achieve the required building functions, is economical, is conducive to structural construction, and the consistency of the structure and the theoretical model, etc. These factors must be comprehensively considered before the structural design.On the other hand, these factors will affect the structural plan and the mechanical analysis model. For example, the change of the building function may change the layout of the building structure, and the different connection modes of the nodes will also cause the mechanical analysis model to change accordingly. Therefore, these factors should be fully considered before the structural design and continuous thinking in the design process.

The design of the space frame structure should ensure that the structure has sufficient reliability within the specified design service life, and safety is the most basic requirement of the space frame structure design.

At present, the safety in the design of space frame structure is to enable the structure to meet the required strength, stiffness and stability requirements under various loads that may be received in the future.

The required strength, stiffness and stability requirements refer to the required values in the specifications and regulations.For specific circumstances that are not given in the specifications and procedures,Should refer to similar space frame engineering experience summaries,comprehensively determine on the basis of certain experimental data and expert consultation.
