Research And Design On Health Monitoring System Of Super High-rise Building Construction

With the development of engineering technology，and social material progress,and accelerated process of urbanization in China，the form of building constructionbecomes newer and complicated．The average height of high buildings in the city risesfast every year，and people pay more attention to the security issues that it brings．Super high-rise building has many problems in its service time，such as costmuch，have long duration，have complicated structure forms and so on，therefore therequest of control of errors in construction period and that of security，applicability anddurability in service period becomes more strict．In order to make the structure worksstability，we have to monitor its situation all the time．The monitoring of super high-rise building structure includes monitoring ofconstruction period and the monitoring of service period．In its construction period，inorder to fit the design，we should control the deformation of components and thedisplacement of structure strictly，and the main work in this period is monitoring thestress and strain of loading components and the vertical displacement of thestructure．In the service period，the structure is under the loads of environment all thetime，therefore the main work is monitoring displacement, acceleration, horizontaldisplacement of structure and the stress-strain of key components．This study comes from a real project that is building，and the project is a superhigh-rise building with the form of huge Frame-outriggers-core tube．The mainstructure of the building will be588meters high，and the top of the building will be646meters high，so it is a landmark building．The main achievements in this paper arepresenting as follows：In this paper，the author analyzed the deformation of components in different partsof construction period，thinking of the influence from shrink and creep of concrete inthis period．This paper analyzed the stress of parts of the components， while thewhole structure is not completed and the stress of components is not stable．This paper analyzed the stress of outrigger trusses and belt trusses under windload in the service period and compared the resistance against wind load in differentkind of components． According to analysis of the structure in construction period and service period，the paper found the better way to choose and arrange sensors so that Structure HealthMonitoring system was well designed．...
