Is there adequate literature on load transfer mechanism of inclined reinforced concrete column between two floor plan?

I think, you will have to establish the necessary basic cases yourself. In my view, an inclined column is different from a vertical one by the fact that the former also undergoes bending moments (due to self-weight) and, above all, will be submitted to more pronounced shear forces. For these cases, you should find sufficient litterature (i.e. columns with bending moments and shear forcces). And I do agree with Patrick: why inclined columns in the first place?!
