Quantity Take Off or QTO is a well known project estimating company serving to the contractors, home builders, architects, design- build firms and sub contractor trade. We are providing estimating service since 2002 with a great chronicle of success.
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%
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
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
Braced and Unbraced Concrete Walls:
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
