| In this paper, with test and theoretical analysis, focusing on reinforced concretebeam longitudinal bar with the inevitable-steel flange in steel reinforced concretestructure intersection of the seismic method performance measures and structuraldesign were studied in light of the actual project.First, through the tests of four different nodes under low cyclic loading, themechanical process and the failure mechanism of SRC-RC beam frame node isstudied. Test process of a detailed description of the test results and a preliminaryanalysis is given. The test results of the bearing capacity and displacement, as well assamples of the stress and strain distributions are given. To further analysis the seismicbehavior of SRC nodes the results provide a large number of experimental data.By theoretical analysis of the influences of the steel flange-defect, the rate wascontrolled within 20%, which is feasible. However, for safety reasons, it is advisableto reinforcing the column flange openings department. In this paper, the designmethod of four forms of reinforcement plates is given completely. Using ABAQUSsoftware analyzing the reinforcement of column flange openings through finiteelement analysis, it is the supplementary for theoretical derivation. It also shows thatthe ABAQUS results of the analysis are reliable.Based on the test results, analysis focus on studying cracking mechanism of thecore areas in the SRC-RC beam frame. And adopting ABAQUS finite elementsoftware, the establishment of a formula of cracking capacity in the core zone isfeasible and then tested by the accuracy of the theoretical formula.Finally, according to test data, under low cyclic loading the shear hysteresiscurve and the skeleton of components ductility of the steel reinforced concrete beam,stiffness and energy attenuation law of degradation are given, then raise the restoringforce model under the low cyclic loading for the preparation of procedures fornonlinear analysis of the entire process of reference.
