Earthquake is a natural calamity that occurs unexpectedly. It is something that can happen anywhere, although there are many earthquake-prone areas in the world. In India too, it happened many times, including in Latur and Gujarat in 1993 and 2001 respectively. After such incidents, strict measures have been taken by the government in implementing standards for constructing earthquake-resistant buildings in areas prone to it.
Factors That Make a Building Earthquake-Resistant
- To design and make earthquake-resistant buildings, it is important to keep them flexible and light. This helps such buildings absorb and distribute their movement’s energy during a quake.
- It is very important to use materials for construction that can bend sans breaking. This helps make it more shock absorbent. Thermo-Mechanically Treated (TMT) bars have excellent properties in this regard. This is because TMT bars have a tough exterior and soft inner core. With high elongation point, they are very durable to withstand just about any seismic shock. Earthquake-resistant TMT bars can be used for reinforcing a building’s structure.
- In areas prone to earthquake, to make properties resistant to it, walls and partitions are kept light. Building thin concrete floors helps too. Shear walls with paneling system as well as braces that channel a side-to-side force down into the foundations also make a building earthquake-resistant.
- During a quake, load-bearing structures undergo brittle failure. A well-constructed and properly designed RCC structure, on the other hand, undergoes ductile failure. Earthquake-resistant properties constructed by following the respective building code are RCC or load-bearing structures. Framed or RCC structures are made of steel and concrete. It is all about making sure the damaged caused to buildings lead to no loss in life, but at the right places and within acceptable ranges. The load in RCC structure is typically carried to the property’s foundation by either shear walls or columns resting on concrete piles.
Kochi may be no earthquake-prone area, as much as is the Idukki district in the north side of Kerala or Wadakkanchery in Thrissur, but measures have been taken by several real estate and public companies to make structures earthquake-resistant in the cultural hub of Ernakulam. An example is Trinity Builders Cochin properties that use RCC structure and deeply piled foundation, thereby complying with safety standards.
