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.

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.

Buying the right TMT steel

Buying right TMT steel grade Fe415

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

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.

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.

Nowadays TMT steels are commonly used in constructions. What is  TMT? Why is it used than other types of steel? Well, before TMT was introduced Mild Steel (MS) bars, Cold Twisted Deformed (CTD) bars were primarily used with concrete for constructing buildings. Those steel were graded Fe 250 but their low strength was a problem for buildings requiring more strength.
