REINFORCEMENT CEMENT CONCRETE

1. Introduction To Design Of
RCC Structures
By,
N.K.KAVYA

2. What is RCC ?
 RCC means Reinforced
Cement Concrete
It is a cement
concrete reinforced with
steel bars , steel plates ,
steel mesh , etc to
increase the tension
withstanding capacity of
the structure.
 The above picture is an example of The Architect
LE CORBUSIER project, where he used RCC like plastic

3. The Advantages of RCC outweigh its
Disadvantages
Advantages
 It is economical in
ultimate cost.
 It is durable, long lasting,
fire resistant and not
attacked by termites.
 Its monolithic character
gives much rigidity to the
structure.
 It can be cast to any
shape.
 Cost of maintenance is
nil.
Disadvantages
Skilled labour is engaged
in the work.
Constant checking is
required.
Scrap value of reinforced
members is almost nil.

4. Components of RCC Structures:
RCC Beams
RCC Columns
RCC Staircase
Foundations
Every component is designed according to the
load it carries and its position in the structure.

5. RCC Beam Design
 RCC Beams are cast in cement
concrete reinforced with steel
bars.
 Beams add rigidity to the structure
 generally carry vertical
gravitational forces but can also be
used to carry horizontal loads.
 There are two types of RCC Beam
Design
1) Singly reinforced beam
2) Doubly reinforced beam

6. Singly Reinforced Beam

7. RCC Column Design
COLUMN:
A Column is a vertical member whose effective length is
greater than 3 times its least lateral dimension carrying
compressive loads .
Column support beams which in turn support walls and
slabs.
The failure of a column results in collapse of the structure
so it should be given more importance.
Generally columns may be SQUARE,CIRCULAR, OR
RECTANGULAR shape.

8. Types of columns
Based on type of REINFORCEMENT:
1) Tied column
2) Spiral column
3) Composite column
Based on type of LOADING:
1) Axially loaded column
2) Eccentrically loaded column
Based on SLENDERNESS RATIO:
1)Short column
2)Long column

9. RCC STAIRCASE DESIGN
STAIRCASE:
Stair consists of series
of steps with landing at
appropriate intervals . The
stretch b/w two landings is
called FLIGHT. The room or
space where stairs are
provided is called staircase.
Types of STAIRCASES:
1) Straight stairs
2) Dog legged stairs
3) Open stair
4)Geometrical stair

10. FOUNDATIONS
 The strength of the
Foundation determines the
life of the structure.
 Design of Foundation
depends upon the type of the
soil , type of structure and its
load.
 Higher the load bearing
capacity of the soil, the larger
the load it could safely carry.
 Foundations are divided into
two types:
1)Shallow Foundations
2)Deep Foundations.
