Optimization Analysis Of Construction Scheme Of Special-shaped Column Super High-rise Hybrid Structure

Since the 21 st century,with the rapid development of my country’s economy and technology,the contemporary archi tectural structure has not only become higher and higher,but also the building structure has become more and more complicated.According to the GB50352-2005 of the "Development of Civil Architecture" : The structure and construction structure of more than 100 meters,no matter what kind of use structure is used,is a super high-rise structure.The design and construction of the design and construction with previous architectural structure specifications cannot be constructed.Therefore,for such ultra-high-level structures,the conventional one-time loading design method cannot meet the safety and rationality of the design.At present,the super high-rise is in its infancy.Most of the analysis of such buildings is the design stage.Considering the wind load and earthquake loads,the basic research of factors generated during construction is lacking,and there are relatively few research on the structure in the construction stage.During the construction process,the construction unit followed the rules and marked the construction according to the drawings.It did not add the overall structure to the transformation of the construction cycle to the construction plan arrangement.The construction method will deform the subject and the connection component design.Therefore,the main structure and the internal force and deformation rules of the components during the construction of the ultra-high-level construction were analyzed.For optimizing the construction process and design process,proposed and adopted the corresponding solution to adjust the multi-floor displacement generated during the construction of the super high-level construction.Economic significance.In response to the above problems,this article has been carried out in the following problems to solve the construction period:1.Combined with the design,construction and usage of ultra-high-level steel frame cylindrical structures,the one-time loading method of traditional structural design and the latest method of testing at this stage are studied.The accuracy is activated by the construction simulation and one loading method,and then the deformation development of the core cylinders,frame columns and connecting components of its main structure is used to find similar laws.Compared with several loading methods,finally use the form of segmented loading to analyze and study this project.2.Taking the Jiangsu case as the research model,the finite element model of the ultra-high-level project is established through the MIdas Gen finite element software,and the research model calculation is activated according to the actual project of the actual project.The degree of influence is the degree of impact on the structure on the structure of the existing construction position displacement and segmented loading method.It studied the vertical deformation pole value of the structure during construction and the stage of completion and use,and the internal force changes of the alien column and explored the cause of the internal force and deformation.And considering the contraction of concrete characteristics,the transformation of the vertical shape is different.The analysis learned that during construction,the deformation of the outer frame column and the core cylinder was presented by the increase of the floor during construction.,Present the trend of large curves in the middle and small curves in the middle;if the additional changes in the characteristics of the concrete characteristics are considered about one-third of the overall deformation of the structure,the impact of concrete characteristics on the vertical displacement value of the ultra-high-level can not be ignored.The design and construction and use should be considered.If not,the simulation results will be inaccurate.3.When the construction of ultra-high-level construction is studied,the law of stress of the layer of truss is strengthened,the overall lifting plan of the truss is analyzed,and the optimal solid time of the truss is analyzed.The research results show that there are certain differences in the stress of the rods at different locations.During the construction stage,the stress of the two string rods gradually becomes larger,and the corner support has gradually increased with the construction stage,but its growth rate is Slightly large,the growth rate of the support to withstand the support of the corner support during the construction process is the fastest;the allowable value of the specification during lifting should be far greater than the overall displacement and stress value of the structure,and meet the deformation requirements of the structure during hanging;the additional stress value value It becomes a positive correlation curve with the conjunction time.From the overall consideration,the best solid time is the conclusion at the end of the time at the end of the construction stage.4.Draw several leading layers of simulation solutions suitable for projects.Compared with the cloud maps and curves of these construction schemes,the best compensation value of vertical deformation at the construction stage is calculated.The final simulation analysis results indicatethat the deformation difference between the core cylinder and the frame column is not the improvement of the leading level.Finally,it is recommended that this project adopts the core of the core cylinder to lead the 6-layer scheme.The minimum and the displacement difference between the two is the smallest;combined with the actual compensation value,the structure of the construction section average method is selected to prepare the structure.5.This article studies the deformation difference and discusses this in various aspects.It should adopt construction simulation analysis in the design process of super high-rise buildings,which provides experience and reference for future projects and has practical significance.
