    Notes: -

    1- RKALC adopts Schlaich Model of Corbel, in which the node at top left of the model (Node2) is bound by the radiused REO Schlaich, Jörg et al. “TOWARD A CONSISTENT DESIGN OF STRUCTURAL CONCRETE.” Pci Journal 32 (1987): 74-150. - We Assume the width of Node 2 = radius of rebar bending which is 5*db

    2- User should design the column for the moments resulting from the corbel loads, in addition to the column loads not accounted for in this application
