Abstract


Steel-concrete composite beam has the advantages of both steel structure and concrete structure, and it would have vast application prospect. However, we emphasize the security and applicability but ignore the durability of structure in structure design. And this would make the structure failure before its service deadline, and lead to a grate economic loss. This article study the deterioration law and damage mechanism by dry and wet cycles quick corrosion experiment in sulfate and chloride case and use commercial finite element software ABAQUS to analyze it. The main contents include:(1)This article aim at three kinds section form of the steel-concrete composite beam, study the route through which sulfate and chloride ions into the steel-concrete composite beam by dry and wet cycles quick corrosion experiment, and compares three section resistance to corrosion of harmful substances ability.(2)The deterioration rule of the materials of the steel and concrete composite beam was analyzed by introducing test and steel and concrete composite beams bending test. The experiment had got the concrete compressive strength of change and quality loss and the stud and steel reducing coefficient of strength and the constitutive relation after corrosion. These provide base for the studying durability of steel and concrete composite beam after corrosion.(3) Study the degradation law of mechanical properties the push-out specimen and the steel-concrete composite beam afer corrosion by dry and wet cycle’s quick corrosion experiment. The mechanical characteristics of them, namely the anti-slip capability, the cross-section strains, the cross-section deflections and the law of the ultimate bearing capacity, are investigated and are compared with the behavior of the control specimen which was not attacked by sulfate and chloride.(4)The finite element method is used in modeling the corrosion steel-concrete composite beam by using the commercial finite element software ABAQUS and the results were compared with the test. The load-deflection curve and load-slip curve obtiained from the FEM are in good agreement with tested. And other parameters of the steel-concrete composite beam are analysed using finite element analysis. It obtains other parameters on the influence law of the steel-concrete composite beam.
