It really doesn't help much. Have a quick check on the stress to be taken by concrete and steel rebars. Basically, we need load bearing shear walls, for tall towers. Structural steel frame work will help in load sharing.

Concrete grades higher than M60, such as M80 and M100, are considered high-strength concrete and are typically used in heavy-duty construction projects such as bridges, high-rise buildings, and nuclear power plants. These high-strength concrete grades are designed to withstand heavy loads, harsh weather conditions, and long-term wear and tear.

It depends on the type of structures. There are several configurations of high-rise structures which are efficient in carrying loads. Mostly the high-rise structures are based on Tube concept given by Fazrul Rahman Khan. The issue is always the floor area which has the highest value and therefore all members are designed in such a way that the wall or columns are of optimum size.
