Research On The Key Construction Technology And Control Measures Of Large Aerial Steel Structure Connecting Corridor

With the development of economic and the increased of people’s cultural and aesthetic levels,the building structure is not adhere to the traditional form of structure, a large number of novel structure, attractive appearance, high-rise complex large-span steel structure came into being. More and more complex structures to diversify, such as ultra-high-rise structure, piece structure, with a conversion layer structure, with a reinforcing layer structure, flat irregular structure, vertical and cantilever structure, or even a combination of many structures. one of them is large span steel structure in this paper.Because different large-span structure, there are a variety of construction methods, the modern common methods of construction process including: high altitude in situ installation method, integral lifting method to enhance the overall law, points(block) the lifting method, slip on counterpoint, etc., and these construction methods has its own characteristics, is not suitable for all structures, so it should be selected depending on the structure of the construction program. The Air Gallery this construction project in modern buildings is very little, there is not too many examples of projects can refer to, And the relevant construction theory is not perfect, so the choose the air corridor construction program is the Key content.This paper analyzes the construction methods used in modern engineering of large-span structures, preferably those that suitable for this project, and a preferred embodiment of reliability checking, and I used the finite element analysis software SAP2000 analysis the construction process simulation, and analyze the internal force and displacement of each member in the construction process, and study the possible problems in the construction process of different construction schemes, And proposed the corresponding solution and control measures.
