Background
The shell structure is a curved surface space structure, and is widely applied to various structures such as pressure vessels, ships, oil tanks, roofs and the like for a long time. In building structures, the building structure is mainly divided into a reticulated shell and a thin shell, wherein the reticulated shell of a steel structure and an aluminum structure is applied more, and the thin shell of the steel structure and the aluminum structure is applied less.
The thin shell structure is a curved thin-wall structure, mainly bears the load perpendicular to the middle surface thereof, and mainly uses the internal force in the middle surface rather than the bending moment to resist the external load, so that the structure has the characteristics of light weight, high strength, reasonable structure and the like. The reinforced concrete structure is made of reinforced concrete materials, and the reinforced concrete structure needs the working procedures of building templates, building reinforcement cages, pouring concrete, maintaining and the like, so that the construction cost is high, the period is long, and the reinforced concrete structure has the defects of great weight, easiness in cracking and difficulty in reinforcing and repairing. Because the steel plate is difficult to carry out curved surface processing and shaping, the steel structure thin shell is rarely applied, so that the application of the thin shell structure is very limited.
The latticed shell structure is a space rod system structure, a grid is formed according to a certain rule on the basis of rod pieces, the space structure is arranged according to the shell structure, force is transferred mainly in an axial force mode of the rod pieces, the latticed shell structure has the characteristics of the rod system structure and the shell structure, and various forms can be realized. The actual engineering mostly adopts steel, and part of the engineering can adopt aluminum alloy materials. Due to the space rod system structure, the node connection mode is a problem which needs to be considered, most nodes have 8-12 rod members which are converged, and the nodes are complex. The reasonable curved surface can make the reticulated shell structure force flow uniform, the structure has larger rigidity, the structural deformation is small, the stability is high, and the material is saved. The disadvantages are that: the nodes are multiple and complex, the enclosure structure plate and the main structure need to be connected through the keel, the construction procedures are multiple, and therefore the construction period is long.
