With the improvement of China's economic and technological level,the technology of reinforcement and reconstruction has gradually developed.The replacement of concrete reinforcement method is usually used for concrete members with low concrete strength and serious defects of local concrete.The core idea of this method is to replace the column with the beam,and its technology development is relatively mature.However,the difficulty of construction and high construction cost are especially prominent when large sections and large axial force components are encountered.In order to solve this problem,this paper mainly uses finite element simulation software to simulation an engineering instance and a standard framework to analyze whether the construction difficulty and construction cost can be reduced by reducing the support.First of all,this article simply introduced the main methods of reinforced concrete structures,common construction quality problems,the construction technology of displacement concrete reinforcement method and the development status of replacement concrete reinforcement method.In addition,the main research methods used in this paper are briefly introduced,namely,althernate path method.Second,to a brief overview of the background of the engineering example,introduces the test plan and test results,using the finite element simulation software ABAQUS finite element analysis was carried out on the test model,compared with the results of the analysis of test results,finally concluded six can be reduced to two pillars safe operation and 8 scaffolds can be used to support unloading of reinforced concrete frame columns.Finally,ABAQUS was used to establish a 15-storey standard framework model,taking the first floor as an example,and destroying the working conditions of many typical localcomponents,Including the long side column,the corner column,the short side column,and the internal column and so on.Analysis results show that when only a pillar strength shortage or damage,no support for replacement concrete construction is to be safe,so the uninstall support can consider to use scaffolding to replace traditional steel column.In this paper,according to the position of the column,the upper load of the displacement column with 54%or 62% is used as the supporting load.
