I am not getting any literature on this topic. As I want to do research on load transfer mechanism so I need some literature on inclined column research?
Also I want to know the scope of future research on this topic
Please help me in this regard
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?!
Yes one of the reasons why literature are scarce is 'why inclined column in the first place?' As far as I know, columns (normal case) would be ideally vertical. If there are any other reasons why inclination is required, usually designer will switch to other alternative such as post-tensioned column, or better, inclined truss system.
Dear Tiong, Thanks for your thoughtful explanation. But, I want to research on this topic as sometimes use of inclined column becomes obvious and what should be the load transfer mechanism in that case. Thanks again.

Thanks for your answer. Sometimes for architectural consideration, column may be inclined and may be preferred to be made of reinforced concrete.
What should be differences if i consider load transfer mechanism of a batter pile to find similarity with inclined RCC column?

The main secondary effect of having inclined columns is that they introduce a horizontal component of the axial load into the beams/floor slabs at each level, so you need to design for these forces.
Also, you need to be careful about additional moments caused within each floor height of column due to eccentricity of vertical loading.
Depending on the amount of inclination, you may also need to cater for net tension in columns in the upper storeys of a multi-storey tower, caused by lateral wind or seismic loading.
They can be designed as vertical columns but taking care to design for the additional moments due to self weight and also the additional shear forces due to the inclination. I am assuming that the incination is not more than 30% to the vertical.
Inclined masonry should be done so that all courses remain horizontal/vertical- in other words, the bottom course should be done on a series of steps, like for stairs.
Conventionally, for designing any column with inclination, one needs to 1st resolve the forces on the inclined column. The column would be designed for a force which is resolved along its longitudinal axis and the moments if any. (the regular method of column design)
So, when you are analyzing this inclined column in Staad, program automatically determines the additional moment due to eccentricity and all the resolved forces developed along the column axis. Now, use the DESIGN COLUMN command to design by the same column design approach.
Just do the structural analysis of the frame that has the inclined column and design the inclined column as a regular column ( short or slender) having the normal force as the axial load and the moments.
This may interest you.
