Abstract:

A generic nonlinear compound frame model is developed and applied for investigation of arching action in reinforced concrete beams. This model takes account of geometrical and material nonlinearities including cracking and crushing of the concrete and yielding of reinforcing steel. Further, a non-local model is adopted to resolve the numerical sensitivity associated with compressive softening of concrete. The effect of support stiffness is incorporated into the formulation by a set of nodal rotational and translational springs that, respectively, represent the flexural and axial stiffness of the supports. The developed model is verified by available experimental data and advanced continuum-based FE models and it is shown that the generic model can predict the ultimate loading capacity and loaddisplacement response of reinforced concrete beams and one-way slabs with reasonable accuracy. Lastly, a parametric study is undertaken and effects of end supports stiffness and concrete compressive strength on development of arching action is investigated.
