Study On Static And Seismic Behavior Of L-Shaped Steel Reinforced Recycled Concrete Columns

The reinforced concrete column of hard wire steel is a new type of steel-skeleton column in a concrete column.This kind of column can effectively improve the internal use area of people’s residence,and enhance the aesthetic and aesthetic experience.The concrete performance is that the column angle is hidden in the wall,which is different from the column angle protruding from the wall inside the traditional residence.At the same time,combined with the previous research results,the new composite column has good bearing capacity and seismic performance.Combined with the current development of China’s national conditions,with the acceleration of the pace of urbanization,the output of construction waste is increasing day by day.How to recycle these construction waste has become a top priority.Based on the above situation,this paper uses the finite element software ABAQUS to combine recycled concrete and L-shaped steel reinforced concrete columns,comprehensively analyzes the static and seismic performance of L-shaped steel reinforced recycled concrete columns,which provides theoretical basis for future research and practical application.The main work of this paper is as followsFinite element software ABAQUS for the simulation of L-shaped steel concrete columns.According to the scale,the attributes of different components are defined,the appropriate interaction relationship is selected,the load is applied according to the simulation needs,and the grid is divided.Finally,a reasonable finite element model is formed and simulated.This paper mainly analyzes the axial compression performance,eccentric compression performance and seismic performance of L-shaped steel reinforced recycled concrete columns.The replacement rate of recycled coarse aggregate,the thickness of steel skeleton and the spacing of stirrups are changed respectively.Finally,the stress conditions of three groups of specimens are analyzed,and the corresponding conclusions are drawn.In this paper,the eccentricity,replacement rate of recycled coarse aggregate,steel thickness and slenderness ratio are changed to analyze the deformation of different specimens,extract the corresponding curves,and finally draw a conclusion.Seismic performance of anisotropic columns has always been an important research object.Most of China is located in the seismic zone,which is a country with frequent earthquakes.If a new type of column wants to be put into use,its seismic performance must be studied in depth.In this paper,by changing the axial compression ratio,the strength coefficient,the substitution rate of the processed aggregate of steel thickness and thickness,the seismic properties of the different types are simulated and the historical and skeletal curves of the different types are compared.The conclusion is that L-shaped steel reinforced recycled concrete column ha s good seismic performance.
