Role of TMT Bars in Earthquake Resistant Construction

The severe earthquake that struck Nepal on April 25, 2015, claimed almost 9,000 lives, many thousands more were injured, and 600,000 structures in Kathmandu and other nearby towns were either damaged or destroyed. The staggering figure of structural damages forces us to believe that it is not the earthquake that kills but poorly built buildings.

Factor of safety in TMT Bars

Factor of safety in TMT bars right steel Fe 415

Engineers build leaving a wide berth of safe loading capacity to construct, let’s get a brief view on how the same is for steel reinforcement bars. We have talked enormously on safety codes listed in IS 1786:2008, in the manufacture of reinforcement bars. Now, let’s discuss how safe loads are calculated in a construction material like reinforcement bars. The min. yield strength a reinforcement bar should have is easily inferred from the grade of the reinforcement purchased. Grade Fe 415 having a min. yield strength of 415 N/mm2, similarly for grade Fe 500 having min. yield strength of 500 N/mm2 and Fe 550 with min. yield strength of 550 N/mm2, so goes for every steel reinforcement grade.

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.

Reinforced steel is the most important component in the construction of buildings. Its multiple advantages in terms of strength and ductility are the sole reason for its increasing popularity and demand. Different versions of reinforced steel bars were introduced such as Mild Steel, HYSD etc. Each had their particular advantages that made it better than its predecessors. However, with the demand for more strength led to introducing stronger and better-reinforced steel bars. One such example is the TMT steel bars.

Facts about TMT reinforced steel

Properties of TMT steel reinforcement bars fe415 rightsteel

When it comes to constructing a building structure, the right set of resources must be used for ensuring the overall life and the integrity of the building. The introduction of reinforcement in construction improved the overall life expectancy of the structure and made them strong enough to withstand the forces of nature. Steel is the primary component used as reinforcement because of its excellent tensile strength, recyclability and similar thermal coefficient of expansion to that of concrete.

Strength, Ductility and TMT Rightsteel Fe415

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.

Thermal Resistance of TMT bars Fe415 rightsteel

Use of Thermo Mechanically Treated (TMT) reinforced bars for construction is now a standard practice. With newer technologies developing, it results in efficient constructions strategies which in turn improves the lifespan and structural integrity of the building structure. However strong the building structure claims to be, in order to for its longevity the building structure has to face several hurdles, even the natural disasters.

TMT Bars And Their Influence

TMT bars have become the backbone of every civil construction out there, they can give structures shapes, strength, and they can be moulded to make slabs, beams and columns as well.
As the expectations and demands of the common man rise with respect to make real estate structures. The need for high-quality materials for building structures has also gone, and this is one of the reasons why TMT bars have taken the centre stage in the construction field. TMT bars come in different grades so as to cater to different needs. These TMT bars have the approval of the Bureau of Indian Standards for building and construction projects. While Fe 415 is the popular choice among homeowners, Fe 500 and Fe 500D have carved out a market for themselves. In the blog, we will take a look Fe 500 and Fe 500D, just like Fe 415 they too are popular with a section of architects and engineers.
