Hi Viewers, welcome to our youtube channel Local Pattadhari
I am Pandi Rajendran, I am happy and excited to see you all by this video
Local Patatharai, the main purpose of starting this youtube channel
is to explain civil engineer concepts in simple manner
Today's topic is Reinforced Concrete
Don't mistake me because of using technical words
Generally reinforced concrete also called as RC house, 
Reinforced Concrete Means Strengthen concrete
May be some one will ask me that concrete is already stronger
then why do we need reinforcement for concrete ?
Whatever the structures may be dam or building…. Two type of stress will be occur
one is compressive stress and other is tensile strss
compressive means pressing and tensile means streching
Concrete is good in compression but not good in tensile
to counter fort those one Reinforced concrete has been discovered
most peoples think this was invented by an engineer
but it was invented by an garderner, his name is Joseph monier
when making his flower pot by cement concrete, it attain the failure at the time
he got an idea to place the steel mesh in between the concrete
it will attain good strength and it become success
The same concept follow in the Construction as a Reinforced concrete
Many people thinking that steel is costly why don't i use only an concrete
we are going to show you the different between them from the demo video
come on let's get into the demo video
in first video you can see the concrete without reinforcement
let's apply the load, while applying load the structure failed easily
the reason for failure is, it can't withstand the tensile stress
now let's apply the load in reinforced concrete
while applying load it failed less then the non reinforced concrete 
in enginnering, steel designed to fail before concrete
names of this process is called as under reinforcement
because of initial steel structural failure it causes
an cracks or deformation indicates the week structure
tells us to evacuate or fix the structure
most people has a doubt about, why don't we use other material instead of steel
nowadays research is going using alternate material of steel as bamboo
but problem with bamboo is they decompose
even it can be maintained perfectly, it can't used in bigger stucture
and also the strength of both concrete and steel is equal steel is used in construction
