AIR TOWER.

OBJECTIVE:

In this design I have depicted a  tall skyscraper having a system installed in it to protect it specifically from being shaken or pulled down by winds.

DESIGN SPECIFICATIONS:

1. The design consists of a series of large circular (slightly curved downwards from the center) plates placed onto each other having many wind channels or air ducts as shown in figure 2. The circular plates actually consists of air ducts built only over each top floors (as the wind blows harder as it reaches the height) of the building.
2. As shown in figure there is a room like structure made in the center of these circular plates to which ducts or channels are connected. And through these air ducts and channels air enters the room and exits into other opposite ducts or channels to be passed out from the building. 
3. As a rule; a moving air acts like a blanket or a sheet i.e; if one molecule of air experiences drift then others in contact too. For example ; if air from a blow dryer is blown into a bag through a wide mouth funnel then not only air from the blow dryer enters the bag but also the still air surrounding the funnel enters the bag; this is because the air moving into the bag is in contact with the still air surrounding the mouth of funnel ; this accelerates the surrounding air also to drift enter the bag.
4. Another example may be given by the drift experienced by the loose clothes as a fast car nearly passes by.
5. So to avoid this phenomenon described in above two examples the center of the plate is made square not funnel like (i.e. not circular or curved which would allow more still air in contact from the square's adjacent sides ducts to enter into the ducts of one side of the square room that is under consideration; as the room depicted above has four sides) to prevent more air to enter into this square room through other ducts connected to this room which could create an imbalance by allowing more still air to enter the building. 
6. Why the whole floor of the ducts is made curved downwards from the center is the key point of the design. Let's consider an example of a bending straw ; as air always blows in straight direction therefore if you blow air into it ; air will apply pressure on the sides of the straw forcing it to become straight. It is assumed that wind blown into straw is quite strong i.e; the wind is generated by mechanical means like wind from blower injected into the straw through jets and the straw itself is not very hard but very much flexible.
7. So put the above example over the building because the air ducts are curved just like a bending straw. And the mechanics that's happening inside the straw is explained below.
8. The line BOA serves as straw or duct inside the circular plates through which air passes. The point O is the center point of the straw or duct. The lines AO and BO are the two sides of the bending straw or ducts. The point M and N serves as the center point of the two sides of the bending straw or ducts. So when the air passes during its first half way AO into the straw or duct it exerts pressure to the sides of the straw forcing AO to become parallel to the x-axis and similarly to the other half of the straw or duct i.e; "BO" to become parallel to the x-axis. Hence both rotating at their respective points M and N and thus AO becomes QR and BO becomes PQ. And the line BOA becomes dotted line PQR.
9. The wind comes in from one side of the circular plates and goes out through the other but the force with which the wind enters the circular plates is divided into two different and opposite directions because this force is utilized in forcing the two half sides of the straw or ducts to become unbending or to become straight outwards to the building edges or facade in opposite directions. 
10. As obvious the circular plates having ducts are made up of rigid and strong material and can not move or become straight from its curved position. But still it will apply pressure over the two half sides of the ducts in opposite directions that is outwards to the building (i.e. the outer ends or mouth of the ducts from which air enters and exits the circular plates). And thus making the building stable , firm and able to withstand all the pressure of the wind coming over the building by dividing the wind's force into two different and opposite directions.
