Hi there, I have recently joined a design firm and was assigned a task of designing wall footing. My senior told me to use "Tributary Area Method" for this specific task. He gave me a list of formulas for various cases such as load transfer from slab to exterior short, exterior long, interior short, interior long beams etc. For rectangular slab sections, these formulas are quite easy to implement, but in cases, where slab isn't rectangular anymore, I don't know how to distribute load in order to get approximate the results. I have attached a pic below, in which I have to design wall footing for bath and kitchen as well. Kindly help me in understanding how this method works.
