Scheme Design and Analysis of Large-Span Special-Shaped Space Steel Connected Structure
This project adopts a large-span irregular steel structure connected to the main frame structure on both sides of the building to achieve the building effect.The height of the main structure is 35.4 m,and the connected span is 81.92 m.Under the guidance of the integrated concept of'investment construction operation',by comparing and analyzing the rationality of orthogonal and square pyramid grid schemes,it is pointed that the use of orthogonal grid scheme for steel structure connections is more reasonable,and the construction and operation are safer and more durable.On the basis of determining the scheme of the connected structure and the connection method between the connected structure and the main structure,finite element software is used to conduct a numerical analysis of the deformation,stress characteristics,component stress,overall stability of the structure,and key nodes of the connected structure.Based on the analysis results,key nodes are constructed and designed to ensure the safety,economy,and rationality of the structural design.
