What is a cyclone?
A cyclone is a type of weather that typically develops in warm tropical oceans and is characterised by wind that revolves around a powerful centre of low atmospheric pressure. In the northern hemisphere, the wind blows anticlockwise, while in the southern hemisphere, it blows in a clockwise direction. Somehow, tropical cyclones are capable of producing winds that are 114 kmph. In rare instances, it exceeds 250 kph.
A wind-driven building collapse
The following list of cyclone-related building failures (which also depend on the pressure within and outside the buildings) is provided:
The internal pressure will rise if there is an opening on the windward side of the building during storms. The building's roof is blown off or perhaps destroyed as a result of this internal pressure and external suction. By including a window on the windward side of the structure, which facilitates easy wind circulation from inside to outside, the internal pressure can be lowered.
The houses may collapse if their lateral faces are exposed to the windward side. Additionally, if the walls and foundation are not completely connected, the building will not be able to endure wind forces, which will cause it to lean towards the wind and eventually collapse.
Another issue during storms is the possibility of light buildings toppling down. The likelihood of the building being blown over increases if it cannot adequately withstand the wind forces.
Extremely Potent Cyclonic Storm Strong tropical storm It is anticipated that Biparjoy would make landfall near to the Pakistan-India border. Biparjoy developed over the eastern central Arabian Sea. The India Meteorological Department (IMD) first discovered a depression on June 6. From there, Biparjoy, the second cyclonic storm and third depression of the 2023 North Indian Ocean cyclone season, developed. The cyclone gradually weakened due to deep flaring convection.
Biparjoy strengthened into a tropical cyclone with a Category 3 equivalent and an exceedingly severe cyclonic storm as it moved faster northeast.
Cyclone Proof Building and Construction
Cyclones are a natural hazard that can cause widespread damage and destruction. In India, cyclones are a major concern, as they can cause billions of dollars in damage and displace millions of people.
There are a number of things that can be done to make buildings more cyclone resistant. These include:
Buildings should be made from strong materials, such as concrete and steel. These materials can withstand the high winds and heavy rains that are associated with cyclones.
Designing the building properly.
The shape and design of the building can also help to make it more cyclone resistant. Buildings should be compact and have a regular shape. They should also have a strong roof that can withstand high winds.
Using proper construction techniques.
The construction of the building should be done using proper techniques. This includes using strong foundations and properly anchoring the building to the ground.
choosing a location for buildings resistant to cyclones
For the design of the cyclone-resistant building, site selection is crucial. As is well known, during cyclones, the wind flows from the sea to the land in a high-velocity, rotatory action. Additionally, in cyclone-prone regions (where the site is closer to the coast), it is advised to build the structures in elevated earth mounds or with cross bracing up to maximum surge level. This is done in order to lessen the risk of flooding.
design factors involving geometry
The performance of the buildings during cyclone time is significantly influenced by their shape. Shapes that are symmetrical are better able to endure wind forces. The most frequently advised shapes are square and rectilinear. This is not to say that asymmetrical shapes or projecting sides are inappropriate in this situation.
By following these guidelines, it is possible to make buildings more cyclone resistant. This can help to protect people and property from the devastating effects of cyclones.
Here are some additional tips for cyclone-resistant building and construction:
- Plant trees around the building. Trees can help to break up the wind and reduce its force.
- Install shutters on windows and doors. Shutters can help to protect the building from flying debris.
- Have a plan in place in case of a cyclone. This plan should include a safe place to go, a way to communicate with family and friends, and a way to get food and water.
By following these tips, you can help to make your home or business more cyclone resistant. This can help to keep you and your loved ones safe during a cyclone.
Cyclones are a serious natural hazard, but there are things that can be done to make buildings more cyclone resistant. By following the guidelines and tips in this blog, you can help to protect your home or business from the devastating effects of cyclones.
