Experimental Investigation and Nonlinear Finite Element Analysis of U-Shaped Steel-Concrete Composite Beam
Abstract:
U-shaped steel –concrete composite beam is a new form of structure components. Through the test of three groups of specimens, the failure modes of structure components, the strain distribution of cross-section, and the load –deformation relationship are analyzed. A preliminary understanding of mechanical characteristics and deformation performance is got from the experimental investigation. The composite beam element is used to conduct nonlinear Finite Element Analysis. Based on the theoretical calculations and experimental investigation, a practical formula of U-shaped steel- concrete composite beam deformation is established. Moreover, the calculated result is in good agreement with the test results.
