AIM AND OBJECTIVE
The reinforced concrete uses extra materials like
steel bars, wooden beams or fibers, along with a wire frame to help mold
the concrete and ensure the safe construction under the worst condition
of the force that may be applied within and outside the building.
The
reinforcement interacts with the concrete, strengthening it and
providing support houses and other structures. The concrete provide
shielding for the steel so it doesn’t corrode as quickly and together
they are a common component in the modern construction.
Therefore,
this project is aimed in ensuring the safety of life and property based
on the use of limit state design code (BS 8110) in understanding the
problem that is involved in design and resolving same appropriately. It
also aimed in knowing the members of the structure and its weight and
the steps taken in achieving the internal and external forces and proper
way of applying the reinforcement for the proper structural stability.
Its
objective includes knowing that concrete tends to be brittle, breaking
easily under sudden stress and crumbling under the influence time and
weather. This makes it difficult to use traditional concrete structures
intended to hold a large amount of weight or last a long time.
Reinforced concrete on the other hand can hold much more weight and does
not wear as easily. Hence most structure built today use reinforced
concrete.
Uses
The reinforced concrete is used in large scale
construction such as bridges and skyscrapers. It was first created for
building construction in the mid 1800s, and soon spread across both
Europe and America. Most major building built by the beginning of the
1900s was created with reinforced concrete.
Consideration: Reinforced
concrete is subjected to the same principles as normal concrete, and
the quality depends on the mixture of the cement and how well it is set.
The extra material used will also cost more, especially if steel bars
are used instead of wood or recycled fiber alternatives. However, the
glass and fiber alternatives can present difficulties on their own by
becoming weaker in a fire.
METHODOLOGY
Reinforced concrete is
concrete in which the reinforcement bars (rebels) reinforcement girders,
plates or fibers have been incorporate to strengthen the concrete in
tension. It was the concrete that is reinforced with steel or iron is
called a reinforced concrete only. Other materials used to reinforced
concrete can be organic and inorganic fibers as well as composite in
different forms. Prior to the invention of reinforcement, concrete was
strong in compression, but weak in tension. Adding reinforcement
crucially increases the strength in tension. The failure strain of
concrete in tension is so low that the reinforcement has to hold the
concrete sections together.
For a strong ductile and durable construction, the reinforcement needs to have the following properties.
High strength
High tensile strain
Good bond to the concrete
Thermal compatibility
Durability in the concrete environment.
