What is
Rebar?
The
fascinating thing about Rebar is its tensile strength(capacity of a
material to withstand loads). Reinforcing Bar commonly known as Rebar
is a steel bar or sometimes a steel wire mesh used in reinforced
concrete to provide it strength.
Alvord
Lake Bridge
The
first ever Rebar bridge was built in 1889 by Ernest L. Ransome(the
inventor of Rebar structure). Alvord Lake Bridge is a tiny bridge
crossing the pedestrian entrance to San Francisco's Golden Gate Park
in America. It is now a civil engineering landmark designated by
American Society of Civil Engineers.
It is
believed that Ransome used cold-twisted square steel bar for
reinforcement placed length-wise in a single arch. It is 64 feet wide
with a span of 20 feet. Today, it stands as a cracked, neglected
structure with concrete deposits in its interior part that have grown
in the later years after its construction.
In 1912,
Ransome published a book named “Reinforced Concrete Buildings” in
which he poured his bitterness about how his use of twisted Rebar was
laughed down by the technical society of California. Frustrated by
the community’s indifference, he left San Francisco thinking no one
here would appreciate his invention of Rebar. Contrary to his
thinking, the Alvord Lake Bridge survived the 1906 earthquake and
fire justifying his initial faith in the method.
As dumpy
as it may seem, the Alvord Lake Bridge is still an exemplary Rebar
structure to the modern world. Being one of the oldest reinforced
concrete structures, it is still serving as a model for all the Rebar
structures that followed till date.
Rebar-Quite
an Intricate Material
The
problem with using Rebar is that it rusts. Even though it is used
with concrete for providing strength, there remains a question to its
sensitivity. When the reinforced steel rusts, its bonding with the
concrete eventually breaks thus resulting in the swelling. A more
advanced version of Rebar is epoxy coated Rebar developed to increase
its longevity. When a Rebar structure is consistently exposed to
natural surroundings as in the case of a highway system, it
eventually gets rusted. Without regular maintenance, even the epoxy
coated Rebar gets worn out.
Rebar
Steel Detailing
Rebar
Steel Detailing
is the process of preparing technical drawings that address the
quantity, placement, and bending shapes with dimensions of
reinforcing steel.
Rebar Steel Detailing
is usually carried out by in-house Rebar fabricators or Rebar
detailing companies. This process is critical to the construction of
concrete structures as it provides the necessary strength to the
building. It requires expert Rebar detailer with sound knowledge of
the field to produce quality
Rebar Detailing Drawings.
