Tall Building Reinforcing Steel Truss Construction Method Andstructure Analysis During The Construction

With the progress of urbanization in China, the tall building in the motherland, thesteel structure has been widely used in high-rise buildings.In order to strengthen thelateral stiffness of the structure, to improve the seismic performance of high-risebuildings will set a few level along the vertical height of strengthening layer, reinforcingsteel truss is representative.In order to improve the level of construction, steel trussstrengthening layer to meet the design requirements, the need to conduct the thoroughresearch to the construction method, structure analysis and the construction period, toensure construction quality.In the process of the construction of a building, the stress ofthe structure are often used to stage performance has great difference, if the impropercontrol of construction, will be likely to cause safety problems, so further study ofstructure stress performance in the construction process, to simulate the constructionprocess of the structure, the structure design and guide the construction is of greatsignificance.Based on the project of guangzhou east tower steel structure engineering, on thebasis of literature study method and qualitative analysis, combined with the finiteelement analysis software to analyze structure construction stage, key research structureconstruction process, the influence of the steel truss strengthening layer mainlycompleted the following work:1Reviewing the development of high-rise buildings, grasp the development trendof high-rise buildings, high-rise construction use function and structure security,highlights the importance of structure selection for high-rise building.2Analysis of tall building horizontal reinforcing mechanism, using literatureresearch, refer to the existing related literature, explore the types of differentstrengthening layer, and various types of applicable conditions and its advantages anddisadvantages, ready for in-depth understanding of horizontal strengthening layer,providing support for follow-up study.3Further study of reinforcing steel truss construction method, through access tothe existing data, combined with engineering practice experience, the steel truss controllayer of material selection, processing factory production, site installation, illustrates theoverall truss layer construction method, and clearly divides the construction steps,guiding the follow-up construction simulation. 4The structural analysis by finite element analysis software for buildingconstruction, load simulation of structure construction process, to solve the internalforce and displacement, demonstrates the feasibility of construction scheme,construction Suggestions are given, guide the construction scheme design,guarantee the safety of the structure in the process of installation and structurereliability after the installation is complete.
