Slim Structures

Why do we need Slim Structure?
As we know that people tend to live near their work place, they are metropolitan centers and cities. This makes the rise in demand of houses and rise in the price. The area in city also becomes less with increase in no. of building and skyscrapers. The rise in no. of floors and increase in no. of such structures have made new design and new techniques in use for high rise with less land.
All this situation made designers and builders to break through and find new solution. The buildings which we see are in standard ratio and they have some restriction with floor area and height of building. Ever since the first high rise many changes have been seen and made accordingly. The super tall but slim sky scraper have become a need for current city situation. cities such as New York, London, Mumbai, Shanghai, Beijing, Tokyo, and many more have the same problem of less buildup area left and high demand. This problem got solved by the concept of Super Slim Structures.

How did this come through?

Designers made a change the length to breadth ratio and making the structure in such a way that it won't be affected by the wind load. The earthquakes were also kept in mind and sufficient damping and isolation of footing is made. The structures are so slim to look and have equivalent strength with pure design and sound structure.
The builders in cities don't get different FSI hence they have to buy the floor area of the adjacent building for period of time to build more floors and they ensure that their view is not blocked by the neighboring building.

Building Super Tall:
432 Park Avenue, New York new slim building
432 Park Avenue

As new construction area inside city is often less big .. builder need to design buildings with a high ratio which makes the building width less and to come up with profit they need by rising of the this slim structures height.

One way is that increase height, but with increase in height there is a increase in wind force acting on the overall structure making it to swing back and forth. To prevent the sway movement building design have holes or some floor spaced open for passage of wind reducing the overall force acting less than usual. It can be seen in many structures now a days such as 432 Park Ave, NYC tower and many Shanghai's high rise buildings and many high rise slim structures are in proposal in Mumbai.

Timber Buildings !?

Timber Buildings !?  Why do we need a timber building? Yes, timber buildings. As on earth human population is on an exponential rise, many and many people are trying to get home in a city where they have easy excess for the workplace for their own living. In the near future, as the population gets more concentrated in cities more and more structures I mean Tall Structures need to be built. Loading Bearing and Comparison So now architects and builders have opted for old Technic of using timber as a building material eliminating concrete and steel. Yes, it is very hard to find this amount of trees but not impossible. It can be grown and regrown as needed. Many projects have been in progress of this idea and it reduces about 75% of carbon emission as compared to concrete and steel structure.



Using timber coming directly from the forest doesn't have the appropriate strength required for a high rise building. So designers came up with the new idea of CLT i.e. Cross Laminate Timber which …
