How to design the reinforced concrete wall

You have to design the Reinforced concrete wall similar to a compression member. Reinforced concrete wall is suitable when there are no beams and load transmitted from the slab is massive or the density of the masonry wall is restrained.
RCC Wall is segregated as follow:
• Plain concrete wall, when rein. < 0.4%
• Reinforced concrete wall, when rein. > 0.4%

Load from slab is transmitted as axial load to wall. When depth is greater, it is known as RC wall. Design is identical to a RC column, breadth is similar to the density of wall and depth is equivalent to 1m. The design of RCC Wall is based on the following factors.
• Axially loaded wall
• Axially loaded with uniaxial bending
Categorization of concrete walls:
1. Plain concrete wall
2. Reinforced concrete wall
Under plain concrete wall, the reinforcement included is under 0.4% of c/s. In reinforced concrete wall, the proportion of employed steel is in excess of 0.4% and is designed in the same way as reinforced concrete columns. Slenderness ratio is equivalent to minimum of (l/t or h/t), where, l denotes effective length of wall, h stands for effective height of wall, t stands for thickness of wall. When < 12, the wall becomes short and if > 12, the wall becomes slender.
Braced and Unbraced Concrete Walls:
Braced: If cross walls are arranged for the walls so as to they can bear lateral load and 2.5% of vertical load, then the wall is defined as braced. If not, the wall is called as unbraced wall.
Note: Other walls under special cases are,
i) Cantilever wall
ii) Shear walls – To withstand lateral loads [Handle flexure created because of lateral loading on the structure, depth is allowed along the transverse direction]
