Mooring space structure system and method for designing same

Abstract

The invention discloses a mooring space structure system and a method for designing the same. The mooring space structure system comprises an inflatable air bag, a support structure and anchor structures. Roofs can be formed by the inflatable air bag, the support structure is used for supporting the inflatable air bag, and the anchor structures are arranged between the bottom of the support structure and the ground in a connected manner, cavities of the inflatable air bag are filled with helium, the integral inflatable air bag is in the shape of a curved surface, and inflatable air bag units are sequentially spliced with one another to form the inflatable air bag; the inflatable airbag units are of double-layer film structures and comprise force holding layers of outer films and air blocking layers of inner films; every two adjacent inflatable air bag units are connected with each other by the corresponding outer films; annular stiffening straps and lifting straps are arranged outside the inflatable air bag units; the support structure comprises vertical supports and connection beams, the vertical supports are parallelly arranged at intervals along the edges of the inflatable air bag, and the connection beams are arranged between the tops of the adjacent vertical supports in a connected manner; the inflatable air bag is connected with the top of the support structure; the anchor structures are gravity anchors. The mooring space structure system and the method have the advantages of reasonable stress and capability of meeting applicability requirements of super-large span structures and super-large closed space structures.

Description

technical field [0001] The invention belongs to the technical field of prestressed space structures, and in particular relates to a mooring space structure system and a design method thereof. Background technique [0002] Traditional space structure systems usually use rigid materials to resist the self-weight and external loads of the structure. The structure is heavy and consumes steel, which is expensive. Therefore, in some long-span engineering fields, people try to find structural solutions with lower cost and faster construction, and the inflatable membrane structure is one of the solutions. In recent decades, the inflatable membrane structure has been widely used in the construction of large-span, light-weight sports buildings, storage buildings, temporary buildings, etc. This kind of inflatable membrane is to inject a certain pressure of air into the closed space to form a stable structure. It relies on air pressure to generate structural rigidity and resist various...
