Design principle of space frame structure
According to the analysis of the current design research results of the space frame
structure, their design principles can be roughly divided into the following aspects:
First of all, the design of space frame structure should conform to the principle of
simplification.Because the space frame structure is a kind of space structure with high order
statically indeterminate, it is impossible to accurately give the transmission or evolution of the
internal force and deformation of the space structure in the design process, so its design is full
of complexity and difficulty.Therefore, scientific research personnel of the construction
industry at home and abroad during the design of space frame structure, usually as far as
possible on the premise of meet the demand of construction of simplified node space frame
structure the space stiffness calculation, the deformation of chord, prompting its design
neither too multifarious, at the same time, both the quality of the project and the stability of
the whole rack space.
Secondly, the design of the space frame structure should be based on the principle of
safety.Safety is the lifeblood of the construction industry. In particular, the grid structure takes
up a large space, so it needs to undertake some high-altitude work no matter in the design or
construction stage. At this time, strict requirements are put forward for safety.On the one
hand, each part of the network structure chord or abdominal bar should be fixed firmly, not
due to external forces under the action of large deformation, so as to ensure the stability of its
structure, to ensure that the construction personnel can be in a safe operating
environment.On the other hand, the calculation of the space frame structure should be in line

with the expected design concept, the stress value of each part is in a good control range,
especially the stress of the base part should have a strong compression capacity, so as to
ensure that the entire space frame structure will not have displacement, affect the
construction progress and safe production.
