Construction 3D printing

3D Printing In Civil Engineering:

This is a core method used in construction or building fabrication. Also called Autonomous Robotic Construction System (ARCS), Large Scale Additive Manufacturing (LSAM) or Freeform Construction (FC), also to refer to subgroups, such as 3D Concrete, used to refer to concrete extrusion technologies.

There are a variety of 3D printing methods and the two main are extrusion, powder bonding, and additive welding. Construction 3D printing is widely used in all sectors such as the commercial, industrial, and public sectors as well. The advantage of this printing technology is faster construction, low-cost labor, accuracy, greater integration of function, and less wastage of building material.

Various Methods:

There are various methods such as on-site/ in-situ fabrication of precast of the building unit using industrial robots. To date by use of 3D printing in construction, components such as cladding and structural panels and columns are built, bridges and civil infrastructure, artificial reefs, and sculptures are made. The technology has been popular in recent years with many companies, including some backed up by prominent names from the construction industry have been started up. And as the years pass by a new generation of machines grew and with every passing generation, the capability of the machine grew much more than previous.

Large-scale cement printing disposes of the need for conventional molding. The pumpability, printability, buildability, and open time of this construction 3D Printing are checked. Construction speed from this technique is such that we can build a house in under 24 hours.

Some Examples Of Construction 3D printing:

The 3D Print Canal House was the first full-scale construction project of its kind to get off the ground.

In Spain, the first pedestrian bridge printed in 3D in the world.

In August 2018 in Palekh, Russia world's first application of additive technology for creating the fountain was done.

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

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

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
