RCC (Reinforced Concrete)
Reinforced cement concrete is made with concrete and steel reinforcement. This concrete is used for compression and supports for tension. For a large range of applications, it is sufficient to consider the uni-axial response of either material.

What Is The Design Of RCC Concrete Structures
Purpose of Using Reinforced Cement Concrete?
-
Plain cement concrete(PCC) has very low tensile strength. The tensile strength of concrete is about one-tenth of its compressive strength. when using Plain cement concrete that time possible to come to crack when tension on the supports.
-
To maintain the tensile strength of concrete we will use reinforcement concrete which can take up the tension stress in the structure.
-
It not only increases the strength but also in preventing temperature and shrinkage.
-
Therefore, reinforcing steel is added to the tension zone to carry all the developed tensile stresses.
Advantages of RCC Concrete
-
This concrete is strong and hard
-
we can make this concrete any shape and size.
-
The raw materials required are readily available.
-
For this concrete, no need for skilled manpower for casting.
-
This Concrete is durable, fire-resisting, and rigid.
-
Concrete requires less maintenance.
Disadvantages of RCC
-
The self-weight of this concrete will be more than the other concrete members
-
If not using the proper steel on the tension zone possibility of a crack will be coming on tension zone.
-
Cracks develop in concrete, also due to shrinkage, creep, temperature, etc. which permit seepage of water into the concrete.
-
This Concrete has very bad insulating properties.
-
Dismantling and reusing concrete elements are mostly not possible.
-
Concrete is brittle in nature and hence has low impact resisting capacity.

What is the Elastic method of design?
The elastic method of design of RCC Concrete members is also called as Working Stress Method. This method of design is based on the materials The method of elastic design of a structure is defined as a method that limits the structural use of the material of the structure up to a certain load at which the maximum stress in extreme fiber reaches the characteristic strength of the material in bending.

What is the Ultimate load design method?
This method is also called as Load Factor Method or ultimate Strength Method. Using this method when the design will fail. This method is calculated only on loads are load factors. The method of ultimate design of a structure is defined as a method that limits the structural use of the material of the construction up to the ultimate load.
What are The Properties of load?
A property of the load is defined as that value of the load that has a 95% probability of not being exceeded during the life of the structure.
Fk = Fm + K Sa
F= characteristic load
Fm= mean load
K = constant=2.645 2.65
Sa = standard deviation for the load
What is permissible stress?
This definition of permissible is the ratio of yield stress to the factor of safety. This is also called Permissible stress Ultimate or Yield strength of materials
What is the Factor of Safety?
The factor of safety is a number used to determine working stress. It is fixed based on the experimental works on the material. It accounts for all uncertainties such as material defects, unforeseen loads, manufacturing defects, unskilled workmanship, temperature effects, etc. The factor of safety is a dimensionless number. It is defined as the ratio of ultimate stress to working stress for brittle materials or yield stress to working stress for a ductile material.
FOS = Ultimate stress Working stress (for brittle material)
What is a Modular Ratio?
The definition of the Modular Ratio is the elastic modular of the rebar to the concrete. It is used to transform the composite section into an equivalent concrete 280 m
Modulus of Elasticity
Modulus of elasticity = E = 5000 √Fck
State the assumption made for the design of RC members in the working stress method.
