For the construction of the structures that are to be used in areas where earthquakes are common, the type of material used has to be given a lot of consideration. This makes the product safe for use and very durable.
TMT bars are well known for their better properties and are abbreviated as thermomechanically treated bars. This makes them the most suitable for such structures. The following are some of the reasons why TMT bars should be used in the construction of earthquake-resistant buildings:
1. Superior Ductility
TMT bars show very good ductility. This is the ability of an object to change its shape without fracturing when under pressure. This property enables the TMT bars to take the energy that results from an earthquake and redistribute the energy. It decreases the chances of structures developing faults. TMT bars are ductile, and this makes it possible for the building to be able to endure powerful earthquakes. This is the reason that prevents the collapse and spares lives and property.
2. High strength
The process of manufacturing TMT bars includes cooling and heat treatment at a very fast pace. This results in a harder outer skin and a softer inner region of the product. This structure is quite useful in offering TMT bars with high tensile strength. This makes them able to cope with the forces that are exerted during an earthquake on a given structure. TMT bars provide better support for the structure, and durability is the main aspect that is improved by using these bars.
3. Enhanced Bonding with Concrete
It needs to be pointed out that TMT bars possess a specific ribbed pattern on the surface of the bars. It also strengthens the kind of bonding they establish with concrete. A strengthened bond makes the steel and concrete work as a single unit during an earthquake. It disperses the seismic forces all over the structure and, hence, makes it act as a whole. TMT bars have a good bond with concrete, which reduces the possibility of cracks and other related structures.
4. Corrosion Resistance
TMT bars are preferred due to their high durability and excellent corrosion resistance. This is because the two are manufactured under a controlled water-cooling process; hence, they will not easily deform. Seismic zones require the utmost protection of the structures from corrosion. Buildings in these areas are mostly subjected to fluctuating environmental conditions. The fact that TMT bars are long-lasting minimizes the frequency of maintenance and repairs on the buildings. This means that there is no compromise on the durability of the structure as a whole.
5. Cost-Effectiveness
TMT bars may cost slightly more than normal steel bars, but the long-term advantages are more beneficial to the users. TMT bars are long-lasting and very strong, and they are not very demanding in terms of maintenance, which means saving a lot of money in the long run. Also, it was found that the incorporation of TMT bars minimizes the chances of structural failure during an earthquake. This, in turn, further reduces repair and replacement costs.
Therefore, TMT bars are highly recommended for use in structures that are to be built or constructed in seismically prone regions. It provides better ductility, high strength, improved adhesion to concrete, corrosion resistance, and is relatively cheaper. These characteristics make it possible for structures developed with TMT bars to stand storms and other forceful movements. This gives protection and comfort to the people who are living in the building.
