Study On The Key Techniques Of The Whole Translation Of Existing Frame Structure Buildings

With the new development concept of China,building translation technology is particularly important in the development of the new era.The overall translation technology of buildings is a project with high technical requirements and great risks,which has not been well applied in most cities in China(based on the specific engineering example of zhengzhou city economic district commission for discipline inspection supervisor committee by the business translation project)as the research background,from the concrete construction of building the overall translation process started,building translation was introduced in detail a few key points the advantages and disadvantages of different methods and combined with the practical characteristics of the project to choose the appropriate translation methods.Before the translation of the building,physical modeling of the building was carried out,and PKPM software was used to set various original design parameters of the model.Through STWEA data analysis in PKPM software,it was found that the shear capacity of the first floor of the building did not meet the requirements in the design code for high-rise concrete structures.Respectively to the static shock through X working condition of horizontal force(regulation)of the displacement,Y to the working condition of static and seismic horizontal force(regulation)of displacement,displacement of X to the working condition of the earthquake,Y to the condition of displacement,X to the wind load conditions of displacement and displacement of Y to the wind load condition through the comparative analysis of the displacement under different working conditions,such as maximum interlayer displacement and maximum interlayer displacement Angle in the building of the tower 1 layer 1.After the analysis of the whole building,the weakest part of the building was found out,and the first floor of the building was strengthened by steel structure reinforcement technology.As the most important carrier in the translation process,the underpinning structure plays a crucial role in the translation of buildings.In this paper,the research on the underpinning structure is mainly described from the stiffness and maximum tensile stress of the underpinning structure.In the process of translation,when the building is completely separated from theoriginal foundation,all the load of the building will be applied to the underpinning structure.Through the finite element analysis of the underpinning structure,it is determined whether the maximum tensile stress and stiffness of the underpinning beam meet the requirements,so as to prevent the concrete from cracking and resist the maximum deformation.In chapter 5,this paper focuses on the new basement as the foundation of the translated building.First analysis of the design and checking calculation of new basement,find out the weak parts of the building,adopt the method of steel cylinder support rail beams are reinforced in the basement,and field sampling was carried out on the basement of backfill soil around and did the compaction experiment,according to the experimental results with the method of notoginseng lime soil in filling and grouting for the processing of backfill soil,finally the finite element analysis was carried out on the basement treatment judgment stiffness and design stress value whether meet the requirements.
