Indian Highways and Major Roads

Highways and Major Roads:

Highways are the most important transportation system part which plays an important role in the development of the area.
The plan of Indian roads was recommended by the Jaykar Committee which said that connecting the remote and urban areas by roads should be the top priority. The first phase was based on the Nagpur road plan.

It was divided as:

1. National Highways
2. State Highways
3. Major District Roads
4. Village Roads
After that, the Bombay Plan was introduced and Expressways were added to the list.

The total highway built to date is around 79232 kilometers connecting the country from north to south and east to west and all major cities and industrial hubs. The Great Golden Quadrilateral was the biggest ever project which was started by the government to connect the various financial and industrial hubs with one road over the country and this project was completed by the year 2012 and are mostly self-controlled due to proper turns and not much intersection over the length.
This highway connects Delhi, Mumbai, Bengaluru, Kolkata which then is connected by the State Highway.

National Highway
State Highway is around 131899 kilometer. These roads are connecting the major internal roads and national highways. The State Highways are the same as the National Highways which are more in number and connect the state's remote area to the cities and help for the agricultural products to reach the market and easy transfer of goods.

Major District Roads are means of connecting the local roads and state highways which are most important. This is built by the municipal cooperation and the authorities which connect the State Highways and major centers of the cities.

Village Roads are the basic roads which are just outside the residential and local buildings and means of internal movement for the locals.

Village Roads
The National and State Highways are mostly built by flexible pavement because the are to long and large which is not economic to built by the cement and concrete mix. The district roads are made by rigid pavement which can be of plain cement-concrete, reinforced concrete or pre-stressed concrete which is more durable and can bear more load and in the long run, is economical. But the village roads are of flexible type due to less traffic load and less movement which is good for that situation.

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
