This is the final blog in the innovation in constructions blog series. The construction of buildings is quite innovating and are truly a marvel. When we compare the current timeline with the ancient timeline, we can see that the number of buildings has risen tremendously over the centuries. With time, different types of innovations in constructions were introduced. This resulted in the construction of better, stronger and taller buildings that are safe to live in.
Constructing buildings is not an easy task, It requires a lot of resources, technical skills, dedication and commitment. When we talk about the resources, the most vital components for constructing buildings are reinforced steel and concrete. Reinforced steel is primarily known for its excellent strength and ductility which provides the necessary strength to withstand the load of the structure. However, there are several factors that can affect the strength of the steel in such a way that it becomes extremely dangerous to the whole structure, and one such factor is rusting.
Our last blog described the TMT steel bars and its importance as reinforcement for the construction of commercial buildings. More specifically, it described the standard IS 1786:2008 that every reinforced steel bar should conform to. The IS standard defines certain guidelines that must be followed when manufacturing the reinforced steel bar.
The introduction of reinforcement drastically changed the phase of construction of building structures of steel. Reinforced steel provided the necessary tensile strength which the concrete lacks. Today, very few constructions are done without using reinforced cement concrete. At the current scenario, the most used reinforced steel bars are the Thermomechanically Treated (TMT) steel reinforced bars. They are preferred for their excellent tensile strength and optimum ductility. The TMT steel bars are of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600.
TMT steel reinforced bars have been used in constructions of building structures for a long time. They are primarily preferred due to the advantages offered in terms of tensile strength and ductility ratio. TMT Steel reinforced bars consists of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600. Because of the availability of different grades and many dealers promoting different versions of the steel reinforced bars, purchasing the right TMT steel reinforced bar is an important task
Natural disasters are usually one of the troublesome challenges for building structures to overcome particularly, the reinforced steel. Natural disasters are of many types, but the most common disaster occurrence in our country are earthquakes. There are many scenarios of structural collapses due to earthquakes. Although the causes can be attributed to several factors such as the age of building structure, lack of maintenance etc, the most important factor to be attributed is the ductile nature.
The Part-I of this blog explained about the two most important factors to be considered in a TMT steel reinforced bar which was Tensile strength and Ductility. Also, a brief introduction of Ductility was described. The hot and soft inner ferrite-pearlite core is responsible for endowing the reinforced bar with optimum ductility. The ductility is not something that should be neglected. It is an integral part of handling the forces or loads of a building structure.
Reinforced steel bars, the supporting platforms in the construction of modern building structures. The current innovation in reinforcement steel is the TMT steel reinforced bars. Known for their unparalleled tensile strength and ductility factor, reinforced steel bars have literally dominated the construction sector in India and all over the world.
In reinforcement of steel bars, splicing technique is generally used to produce a single large reinforced steel bar by joining two similar length reinforced bars and wiring them.
The current construction of building structures is dominated by reinforced steel. Reinforced steel bars are preferred for their unmatched tensile strength which the concrete is weak to provide and ductility factor, that helps to withstand the load of the structure. There are different grades and different diameters (mm) of the reinforced bars in the current market namely Fe 415, Fe 500, Fe 550 and Fe 600.
