| CUBIC Space frame structure is one of the widely used structural forms in a space grid structure.A large-span square flat four-slope water concrete cubic Space frame is a new three-dimensional space grid structure.The structure has good structural strength and rigidity,is a reinforced concrete space grid structure that is structurally safe,economical in construction,and reasonable in layout,and has broad application prospects.This paper first reviews the development history and application status of the CUBIC Space frame structure and introduces the analysis and calculation methods of the fasting structure,and analyzes the force characteristics of the structure.Based on theory and finite element analysis software such as ANSYS and MIDAS,a large-span square four-slope concrete cubic Space frame was modeled.Investigated the static and dynamic characteristics of the structure,and the modeling dimensions of its structural members were analyzed based on the effects of static and dynamic aspects.The large-span square flat four-slope water CUBIC Space frame was discussed in a spatial grid structure system.Dynamic analysis of a three-story,long-span building composed of a concrete empty-web grid and an empty-web sandwich panel.The research results show that: large-span square flat four-slope concrete CUBIC Space frame structure have good mechanical properties,and the overall stiffness of the hollow webs and hollow webs is mainly controlled by the substructure,which has good seismic performance.In view of the fact that the new large-span square flat four-slope water-concrete CUBIC Space frame roof structure has few practical engineering applications at present,the research results of this paper can provide a certain reference value for the future research of this type of structure,which is conducive to promoting this new type of large-span Promotion of roof structure. |
