Experimental Study On Compression Of SRRC Column With Different Substitution Rate

Steel concrete composite structural member is a steel embedded in reinforced concretestructure in the form of an independent. This structure is made of steel, the mainreinforcement, stirrups and concrete combination, namely the core part is the main type ofsteel. Usually steel reinforced concrete and steel reinforced concrete or reinforced concrete(Steel Reinforced Concrete). Although in recent years the research of regeneration concreteis a hot issue in the academic session, on the basic performance of recycled concrete researchis more, is more mature, however on recycled concrete structural member with respect to therelatively few studies, and is still in the exploration stage, especially in the recycled concretecolumn is less, especially in steel reinforced recycled concrete column research direction,domestic research literature belongs to the initial stage, so the steel reinforced recycledconcrete research has important significance, combined with the contemporary socialdevelopment and the present stage of steel reinforced recycled concrete research status,considered in the actual engineering of the regenerated concrete utilization, of steel recycledconcrete compression bearing capacity.The main research work includes the following content: firstly, summarize the domesticand foreign literatures on recycled concrete and recycled concrete columns and other aspectsof the research content, draw on recycled concrete and recycled application situation, summedup the recycled concrete specification and standard. Secondly, through experiments onrecycled concrete and normal concrete basic properties of recycled concrete, this paper usethe availability, calculation of the strength and modulus of recycled concrete. Again throughthe pouring of6steel concrete column specimens, the specimens were collected test oncompression performance, experimental data, as observed in the experiments column failureprocess, crack etc.. By the end of the steel reinforced recycled concrete column and the steelconcrete compression test results, analysis of steel recycled concrete columns under eccentricloading performance of the main influence factors, the steel reinforced recycled concretecolumn in various materials compressive stress-strain curve, and the calculation of steelreinforced concrete column bearing capacity and drawing correlation of N-M curve, draw thecorresponding conclusions about future steel reinforced recycled concrete research andapplication to provide reference.The conclusion of this paper: the steel recycled concrete concept, carried out on theregeneration concrete basic compression experiment, different substitution rate ofcompressive strength of recycled concrete can be used in the experiment, member. For thereplacement rate of different type of steel, recycled concrete column bearing capacity changeis bigger, the same eccentricity are replaced at a rate of50%in the column bearing capacitywas significantly higher than that of100%, with the substitution rate of different eccentricdistance with increasing eccentricity, reduce the carrying capacity of the. Steel bearingcapacity of recycled concrete the experimental value and theoretical value changes a little, the M-N curve, different substitution rate of steel concrete column bearing capacity value in thetheory of safety value range.
