like figure 2 , image 3 As shown, the prestressed tube truss structure 2' is mainly composed of the main arch 21' (also called "main truss"), longitudinal connection truss 22' (also called "secondary truss"), prestressed cables 23', foundation, etc. Partial composition, this kind of structural system itself has obvious distinctions between primary and secondary, strength and weakness, and the interdependence between components is strong, resulting in poor progressive collapse resistance of the structural system

Embodiment Construction
[0038] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.
[0039] like Figure 4 , Figure 5 As shown, the present invention provides a combined structural system of a prestressed pipe truss and a reticulated shell, which includes a reticulated shell structure 1 and a prestressed pipe truss structure. The prestressed pipe truss structure includes a pipe truss structure 2 and a prestressed cable 3. Both ends of the stress cables 3 are respectively connected to the pipe truss structure 2, the prestress cables 3 are located at the lower part of the pipe truss structure 2, and the prestress cables 3 are horizontally connected between the two ends of the pipe truss structure 2, for example; And connected above the pipe truss structure 2, wherein the prestressed pipe truss structure composed ...

The invention provides a pre-stressed pipe truss and net shell combined structure system and building structure. The pre-stressed pipe truss and net shell combined structure system comprises a pre-stressed pipe truss structure and a net shell structure, the pre-stressed pipe truss structure comprises a pipe truss structure and a pre-stressed cable, two ends of the pre-stressed cable are connectedwith the pipe truss structure, the net shell structure is connected above the pipe truss structure in a covering manner, a roof structure of the building structure is provided with the pre-stressed pipe truss and net shell combined structure system. According to the pre-stressed pipe truss and net shell combined structure system and building structure, a pre-stressed pipe truss structure and a netshell structure are combined, the economic application span range of the net shell structure can be widened, and the shortcomings of poor integrality and weak continuous collapse resisting ability ofthe pre-stressed pipe truss structure can be overcome.
Description
technical field [0001] The invention relates to a space steel structure system, in particular to a structure system combined with a prestressed pipe truss and a reticulated shell and a building structure. Background technique [0002] The generally economically applicable span of common reticulated shell structure system is less than 130m, such as figure 1 As shown, within this span range, steel is economical for ordinary reticulated shell structure 1'. On the one hand, the reasonable curve makes the force flow of the structure uniform, so that the structure has greater rigidity while saving steel, and the overall stability is good; on the other hand, the net The rods and spherical joints in the shell structure can be prefabricated in the factory to realize factory production, with good comprehensive economic indicators and short construction period. However, when the span exceeds the economically applicable span range of reticulated shells, steel for ordinary reticulated s...
