Study On Mechanical Behavior Of Joints Made Of Steel Beam And Reinforced Concrete Colums

The frame that constituted by steel beam and reinforced concrete colums is a kind of new combination form,this text will emphasize on the research of the breakage appearance and the anti- earthquakes of the combine form joints.First,ANSYS finite element software for the simulation and analysis of the trial.Define each kind of material unit selection,the parameter and the destruction criterion in the simulation process.Use the software of ANSYS analysis steel beam-reinforced concrete colums in each of break process,anti-power and the stress-strain state of regional joints beam, hoops,concrete.This text design two speciments which steel beams universal of steel beam-reinforced concrete colums frame middle joints,the speciments measures tectonic:The joints area inside level hoop steel and encrypt,establish plank on the joints two sides.Buries the strain gauge in advance on ection web plate wing and hoop of joints area,Makes corresponding waterproof processing,observation joints area stress strained condition.Carries wing place the arrangement tension bar sensor on the beam edge of joints area to observ steel girder stress process.Through installed itself data collect system to collect information of power and displacement,make use of the collect data and ask for the help from the software to drew hysteresis curve of colums top of level power and level displacement,according to the curve analysis its anti-earthquake function.In the end,through trial research and theories analyze we can know:Medium colums joints that this text experiments result that the joints core area belong to shear breakage,its hysteresis curve between the steel joints and the concrete joints,in the process of carry on experiment add carry,flange keep flexibility, when joints will break express yield,as a result come to the purpose of break begin from the joints core area,and can analyze the whole process of the joints area to break;on the foundation textual on trial data,analyze each part of joints in anti-shear the function.Use this article tentative data, proposed earthquake resistance capacity computational method of the steel beam-concrete column joints.
