As we entered a new millennium, we are witnessing
more natural catastrophic incidences than ever. The year started with
wildfires, earthquakes and everything else. The consequences of global warming are
manifold. These events can wreak havoc on human
life, wildlife and the environment. Together we can make a difference in
combating the disastrous effects of these unforeseen events. However,
prevention is also the best way to go about it.
Earthquakes have become a regular
occurrence causing massive damages. While no structure can be fully earthquake
proof, engineers are using innovative techniques and designs to safeguard new
structures. These construction techniques help to reduce destruction and save
precious lives. An earthquake with a magnitude of 6 Richter scale and above can
damage any building. Lack of habitable land and increasing human population are
leading to the construction of high-rise buildings that stand at a higher risk
of being destroyed by earthquakes. It is also easier to evacuate people through
stairs in a low-rise building compared to a high-rise building. However, modern
evacuation techniques are often inbuilt in tall buildings. A popular example
would be the World trade centre tragedy in 2011, many people could not make it
to the ground floor because of the height of the building. Engineers are
striving to create partially earthquake-resistant structures. Unreinforced
bricks plastered with mortar are dangerous structures and can be reduced to
rubble in case of any seismic shock waves. MP Birla is one of the best cement companies in India. The major types of cement manufactured by MP Birla are
OPC, PSC, and PPC.
Portland Slag cement is used to create
strong and durable structures. If you are constructing your building, get the
best durable Portland cement for general construction work.
The Burj Khalifa in Dubai is the
tallest mega-structure in the world standing at a height of 2722 feet. This
massive skyscraper can withstand earthquakes up to 7 Richter scale. It is built
on a 52-foot-deep steel and concrete foundation. The vertical and horizontal
loadings are supported by a unique truss system, making it resistant to
torsional movements. Shanghai tower with a height of 2000 feet, is the second
tallest building in the world. The site is primarily filled with soft,
clay-based soil. To make this structure earthquake resistant, engineers
incorporated 980 piles and secured 2.15 million cubic feet of reinforced
concrete. It also consists of a tuned mass damper to control swaying during
earthquake or high winds. A series of shock absorbers helps in optimal
counterbalancing. Taipei 101 located in Taiwan is one of the tallest structures
in the world. It has a massive internal damper to control swaying and minimize
the possibility of structural damage, in case of an earthquake. Recently a few
Earthquakes occurred in Northern Indian region.
The foundation of any building is the
most important of any other part. Stay updated with the latest architectural
innovations in the construction industry.
