Analysis Of Key Technologies For Construction And Design Of Super High-rise Hydraulic Climbing Formwork

With the rapid development of China's economy and the increase in urban population,high-rise and super-high-rise buildings have sprung up in cities,and the construction process of the construction industry has developed.Compared with the traditional scaffolding structure,hydraulic climbing formwork technology is an advanced technology in construction and is widely used in high-rise and super-high-rise core tube construction.The hydraulic climbing formwork is a high-altitude operation in the construction state and the climbing state,which is a dangerous project.Therefore,the safety of its structure in design and use is particularly important.It is necessary to further study the hydraulic climbing formwork in terms of structural safety and economy.Explore sexual aspects.Based on this background,this paper discusses the economics of the structure on the basis of ensuring the safety of the hydraulic climbing formwork.This article combines the current BIM technology and hydraulic climbing formwork research,with a super high-rise core tube building in Shenzhen as the background,using BIM technology and ANSYS software to carry out 3D modeling,static analysis and structural optimization of the hydraulic climbing formwork,and finally analyze the core The measured data of the cylinder provides a basis for the design and optimization of the hydraulic climbing formwork.The main contents of this study are as follows:(1)Based on the BIM technology platform to establish a three-dimensional hydraulic climbing formwork,a detailed introduction to the process of BIM building hydraulic climbing formwork.Aiming at the safety of hydraulic climbing formwork,combining Revit and ANSYS software,the method of model replacement between BIM and ANSYS was explored,and the safety analysis of the hydraulic climbing formwork was carried out.Based on the analysis results,the optimization variables of the hydraulic climbing formwork are studied to prepare for the next structural optimization.(2)Analyze the basic theories of four optimization methods: multi-objective genetic algorithm(MOGA),screening method(Screening),sequence quadratic programming method(SQP)and mixed integer sequence quadratic programming method(MISQP),based on ANSYS The software implements four optimization methods to optimize the hydraulic climbing formwork and find the optimal structural scheme.(3)Based on the measured data of the inner cylinder of the hydraulic climbing formwork,explore the stress condition of the hydraulic climbing formwork in the actual project.The vibrating wire surface strain gauge is used to monitor the main load-bearing members of the inner cylinder of the hydraulic climbing formwork,and the most unfavorable load of the hydraulic climbing formwork is analyzed according to the monitoring results,and data are provided for the design and optimization of the hydraulic climbing formwork.
