The Simulation Analysis Of The Interface Condition And Requirements Of SRC Composite Beams Based On Bond-slip Theory

Based on the bond-slip constitutive relations theoretical analysis, the SRC structure characteristic and application are introduced. The present research situation of bond-slip relations is summarized at home and abroad. The bond-slip constitutive relations of composite SRC beam are analyzed by the two situations of setting and no setting stud shear connectors and the analysis results are compared.In order to take the interaction between the steel and the concrete into account, combination 39 elements were used to simulate the three directional interactions. The finite element analysis numerical simulations by ANSYS program of the SRC composite beam are made comparing with the test results. The simulation results were compared with the experimental results, from which the established bond-slip constitutive relations model was verified. The methods and skills of nonlinear FEM numerical simulation by ANSYS program used in SRC structures were summarized and presented.Based on above and compared with the actual structure measure of existing project, the detailing requirements and the related proposals of the stud shear connectors are also given for the guidance of engineering design and practical application.
