Scope

1.0.1 This standard is formulated with a view to implementing the national technical and
economic policies in the design and construction of space frame structure and making the
design to be of advanced technology, safety and usability, economy and rationality and high
quality.
1.0.2 This standard is applicable to the design and construction of space frame structure
composed of steel members, including space truss, single layer or double-layer latticed shell
and spatial truss.
1.0.3 In the design of space frame structure, the reasonable structure scheme, frame/grid
layout and structure measures shall be selected according to the actual situation and the
comprehensive consideration shall be taken for material supply, processing fabrication and
onsite construction, to ensure better technical and economic effects.
1.0.4 Suspended crane shall not be arranged for single-layer latticed shell structure. Space
truss and double-layer latticed shell structures may directly withstand the suspended crane
load at Level A3 or higher level. In case the cycle times of the stress variation is larger than or
equal to 5×104, the fatigue analysis shall be conducted, and the allowable stress amplitude and
the structure shall be determined by special test.
1.0.5 The design and construction of space frame structure shall comply with the
requirements in the current relevant national standards besides this standard.
