please, see the following photo and comment about the Tree R.C. Column
It is a very elegant, efficient and good way of minimising the use of many columns, giving a large open space. The key will be the careful and correct design of the tapered cantilever beams and the central column, as the loading from the upper floor will be very substantial. The central column will be subjected to multi-axial bending moments; and of course the large axial force.
It does go against one important principle of structural design which is redundancy but at the same time creates one single point of reference - or a few controlling parameters for optimising stability and strength. I can imaging the foundation would mirror the tree reinforced column.
I think it can survive.
From architectural point of view: it is creative
From structural point of view: it is dangerous
I think the designer considered everything thing related to load combinations and load distribution in additional to an important issue that the building should be construed away of seismic zones.
Those cantilever beams probably have to be prestressed. It is difficult to imagine how big foundation can be under this column. From the struktural point of view I don't like such solution - what about accidental loads? How can we protect this structure against progressive collapse?
Ahmed El-barbary ...
Agree with Mohannad H. Al-Sherrawi .... But anyway.. structural engineer designer will be there to give the best, safe, economic design...
Good question.. Please share me the best answer might you trust...
