TMT steel bars protect against earthquakes and other types of natural disasters. TMT bars are most often corrosion-free, which helps obtain a longer life for your structure. They must have high-strength reinforcement with a tough outer core and a milder inner core. Earthquake Resistant TMT Bars are the best choice for houses that are built in seismic-prone areas.
Some key qualities that good TMT bars feature include ductility, elongation, workability, and strength. The two primary properties of TMT bars are ductility and elongation, which retains the structural integrity during an earthquake by absorbing the shock without breaking.
During an earthquake, the TMT bar’s soft- core allows a slight tilting action, while the steel bar’s strong outside brings the structure back to the primary position. The elongation and ductile characteristics better adjust to tensile stress, or inelastic strains, during seismic activities and their aftershocks.
What You Must Consider While Selecting Earthquake Resistant TMT Bars?
TMT Bars have suitable mechanical properties such as high elongation percentage and top yield strength, which are important for determining the bar’s flexural capacity. A TMT bar manufacturing company also uses high-tech block mills, which safeguard against manufacturing faults, guaranteeing peace of mind.
How Will You Know Whether A TMT Bar Is Truly Earthquake-Proof or Not?
The BIS, the Bureau of India Standards, has specified certain grades for TMT bars, like Fe600, Fe500D, Fe500, Fe550, Fe415D, and Fe415. According to various studies, Fe 415 and Fe 500 have the proper mixture of tensile strength and ductility, which makes them a top pick for constructions in regions that are seismic-prone.
As reported by the NCS, India is in a High Seismic Zone, with over 56 percent of its land prone to low-to-severe tremors. Therefore, when it comes to ensuring the safety of your loved ones, choose the right TMT bars for your home. (source)
Some Features of TMT Bars That Make Them Especially Useful for Earthquake-prone Areas
Ductility –
Ductility is one of the most important features of TMT bars regarding seismic resistance. As TMT bars have a unique manufacturing process, they can bring a higher level of flexibility to the structure. This makes sure when the building gets shaken by the earthquake; it can retain its structure.
Elongation-
Along with a high level of ductility, TMT bars should also have great elongation properties. This means during the event of an earthquake; the elastic strains will be handled in a better way. Due to a high elongation index, TMT steel bars would absorb the shocks, and the damage to the building would be minimal.
Corrosion resistance –
Corrosion also plays a part in weakening the structure. Naturally, compromised structures, prone to corrosion, are the first to collapse during a seismic event. TMT bars have enhanced anti-corrosion properties and come with a unique cross-rib formation, ensuring that the concrete is always tightly bonded with the steel bars. Corrosion Resistance TMT Bars keep buildings standing even under high stress when matched with their superior bendability.
Design –
The cross-design formation in the TMT bars is there because it plays an important role in providing shock resistance during a seismic event. The cross-rib formation on the TMT steel bars makes sure that the structure gels up well with the concrete, and the concrete is always tightly bound with the structure.
TMT Steel bars are a game-changer when it came to increasing the structural integrity of buildings! Nowadays, TMT bars have become the only option for construction projects. Its advanced technology gives the structure extra strength, flexibility, and weldability. TMT bars are much lightweight than regular steel bars, so your structure will need less steel. This will successfully make your building more cost-efficient and stronger. More importantly, it has flexibility which means TMT bars give more structural stability in the case of natural disasters. Thanks to its utmost strength and ductility, TMT bars are earthquake resistant, as they can take additional bending and buckling without failing the structural integrity of the building.
