    Abstract
  • In order to investigate the flexural performance of steel and concrete composite girders with circle tubular flange, the flexural failure tests of three composite girders with circle tubular flange were carried out by static loading, and the failure processes and failure characteristics of test girders were obtained.Based on considering the damage plasticity constitution of concrete, the slippages and fractures of studs, the nonlinear finite element models of composite girders wereconducted and validated by using experimental results.The width of lower flange of steel girder, the thickness of concrete slab and the diameter of tube were taken as main structural parameters, and the mechanical properties of 48 numerical model composite girders with circle tubular flange based on orthogonal design were calculated.According to the flexural behaviors of test girders and numerical model girders, the ultimate flexural bearing capacity formulas of composite girders with circle tubular flange were established based on the simplified plastic theory.By the numerical calculation results regression, the empirical expression of displacement ductile coefficient for composite girders was proposed.Computation result shows that the strength and deflection ratios of the numerical models to the test girders are 0.99-1.03 and 0.87-1.09, separately, so the moment-deflection computation curves are in good agreement with the experimental curves, which demonstrates that the whole processes of flexural behaviors for composite girders with circle tubular flange can be simulated accurately by using the numerical models.The ultimate flexural strength of composite girder with circle tubular flange increases with the increase of lower flange width of steel girder and the thickness of concrete slab, and changes little with the diameter of tube.The displacement ductile coefficient increases linearly with the increase of thickness of concrete slab and diameter square of tube, whereas reduces linearly with the increase of lower flange width of steel girder.For the model girders with different plasticity statuses, the displacement ductile coefficients are 3.16-7.19, which indicates good ductility.The ratios of ultimate flexural strengths computed by using the proposed simplified formulas and the numerical model composite girders are 0.91-1.09, and the average ratio is 0.98, so the computation result by using the formulas is accurate.To ensure the appropriate ductility of composite girder with circle tubular flange, it is suggested that the displacement ductile coefficient is greater than 3.5.
