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. 2 Terms and Symbols 2.1 Terms 2.1.1 Space grid structure, space frame, space latticed structure Spatial structure formed of member and member bar arranged in a certain rule by joint connection, including space truss, curved latticed shell and spatial truss 2.1.2 Space truss, space grid Flat plate type or slight curved spatial trussing structure formed of member bars arranged in a certain rule by joint connection, mainly bearing the integral bending internal force 2.1.3 Intersecting lattice truss system System formed of two-way or three-way intersecting lattice trusses 2.1.4 Square pyramid system System formed of square pyramids as basic unit 2.1.5 Triangular pyramid system System formed of triangular pyramids as basic unit 2.1.6 Composite space truss Flat lattice truss structure formed by reinforced concrete slab as upper chord member and steel web member and bottom chord bar 2.1.7 Latticed shell, reticulated shell Curved spatial trussing structure or beam structure formed of member bars arranged in a certain rule by joint connection, mainly bearing the integral thin film internal force 2.1.8 Spherical latticed shell, braced dome Single-layer or double-layer latticed shell structure with spherical appearance 2.1.9 Cylindrical latticed shell, braced vault Single-layer or double-layer latticed shell structure with cylindric surface appearance 2.1.10 Hyperbolic paraboloid latticed shell Single-layer or double-layer latticed shell structure with the appearance of hyperbolic paraboloid 2.1.11 Elliptic paraboloid latticed shell Single-layer or double-layer latticed shell structure with the appearance of elliptic paraboloid 2.1.12 Lamella grid Rhombic grid cell formed of two-way heterotropic member bars 2.1.13 Ribbed type Trapezia grid cell formed of radial and circumferential member bar on spherical face 2.1.14 Ribbed type with diagonal bars (Schwedler dome) Triangular grid cell formed of radial, circumferential and diagonal member on spherical face 2.1.15 Three-way grid Equilateral triangle grid cell formed of three-way member bars 2.1.16 Fan shape three-way grid (Kiewitt dome) Triangular grid cell formed of circumferential member bar jointly with the lamella grid formed of parallel rods in n (n=6, 8) sector curved surfaces divided radially on a spherical face 2.1.17 Sunflower shape three-way grid Triangular grid cell formed of circumferential member bars jointly with the lamella grid formed of two-way radiated heterotropic member bars on a spherical face 2.1.18 Geodesic type Three-way grid cells that form the grids on the base of the equilateral spherical triangle corresponding to the regular 20-polyhedron inscribed to the sphere 2.1.19 Composite latticed shell Latticed shell structure formed by reinforced concrete slab as upper chord member and steel web member and bottom chord bar 2.1.20 Spatial truss Lattice truss with triangular or tetragonal sectional area formed of upper chord, web member and bottom chord bar 2.1.21 Welded hollow spherical joint Connecting joint with a hollow sphere welded of two hot stamping steel hemispheres (ribbed or not ribbed) by welding 2.1.22 Bolted spherical joint Mechanically assembled joints formed of spare parts including bolted sphere, high-strength bolt, pin (or screw), sleeve, cone-head or closing plate 2.1.23 Embedded hub joint Mechanically assembled joints formed of spare parts including column hub body, bar end embedment, upper and lower cover plates, centre bolt, flat washer and spring washer 2.1.24 Cast steel joint Spatial joint made by casting technique, used for complicated shape or load-carrying condition 2.1.25 Pin axis joint Mechanically assembled joints with unidirectional rotation function, formed of pin axis and pin plate
