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.

Great Man-Made River (GMR)

Libya's Great Man Made River: The Great Man-Made River in Libya is one of the most ambitious Civil Engineering Project in history of mankind.  In the year 1953, the Libya Government found out not only vast oil reserves but also vast quantity of fresh water locked under the strata, most of the water was trapped around 7000-30000 years ago which is divided in 4 different basins. The first basin is named Kufra basin which is neat Egypt Border which covers almost 35000 sq kilometer which is quite deep around 2000 m deep. The other basin is in Sirte Basin which cover 10000 sq kilometer, third in Murzuk Basin and the last in Jabal Fezzan Basin covering 4800 sq kilometers area.  The GMR project will be used to transfer water to North of the country to provide water for irrigation purpose for more than 6 million  people. This will be a changing point  for Libya and the Colonel Muammar Gaddafi called it the Eighth Wonder of World. The work started in 1984 of the project and estimated to be

DDSS - Roof Truss

Design Of Roof Truss: If load from purlin, false ceiling etc are applied in between the nodes, then principal rafters or main ties are designed for combined stresses from bending and axial loads. IS 800 - 2007 provides general design procedure for the angle Purlins conforming to steel grade of Fe 410 of O, S, W  and not exceeding slope more than 30 degree based on live load of 750 N/m2. Loads on Trusses: Dead Load, Live Load, Wind Load and Snow Load are types of loads on the truss. The main in Design of Truss in small truss and some Industrial Truss. Dead Load (DL): If spacing of Truss is 4 m and pitch of truss is 1:4 then self weight of the truss is taken as, w = (l/3+6) of plan area .... in kN/m2. Then add all the dead loads with this such as GI sheet, AC sheet and Purlins weight. Then multiply with the plan area to get the actual DL. Live Load(LL): If the angle is less than 10 degree, then the LL will be directly taken as 750 N/m2. If slope of truss is more than 10 degree, live load

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 the 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 Tim
