If 2 rectangular beam sections of the same material share load effects, moment sharing is distributed by the ratio of respective member stiffness. That is each individual I (moment of inertia) divided by the total or summed moment of inertia. How is shear sharing distributed? Is it by a ratio of Q (first moment of area), A (area), I (moment of inertia), or something else?
