Buildings
A building is a permanent construction or structure that is built for human habitation. It may be for housing, commerce, industry, education, or other purpose. Questions pertaining to the history and construction of structures which house people at work or home are found in this category.

Tie wire should be used always, not welding. Rebar integrety is comprimised when welded. A specific grade of rebar, A706, exists for welding but otherwise, its is not advised that rebar be welded. See below:
Q: When is it appropriate to use welded splices in the field? A: The ACI 318 Building Code requires the architect/engineer to indicate the type and location of welded splices of reinforcing bars on the project drawings or in the project specifications. The ACI 318 Building Code further requires that all welded splices should conform to the Structural Welding Code for Reinforcing Steel published by the American Welding Society, which requires the project contractor to prepare written welding procedure specifications (WPS) for all welded splices. These will depend heavily on the assessment of carbon-equivalent (CE) and other rebar properties as determined by the mill test reports that accompany each shipment. For more information about welding reinforcing steel, see the American Welding Society's (AWS)
Structural Welding Code for Reinforcing Steel.
Q: Can tack welding be used to hold reinforcing bars during assembly? A: Field tack welding should never be used as a substitute for tying in assembling and securing reinforcing bars. Rare exceptions are specified in the International Building Code.

Where is the Onslow County Fair being held?
It's held at the Jacksonville Fairgrounds facility, which is off Broadhurst Road just south of Ocean Highway.
What are the examples for Group Technology?
group technology allows for more people to be involved in a sexual position
drainage basins are rivers and strems all conected to one large river
take the Mississippi river for an example
it is so long and big with a bunch of littler rivers and streams branching off of it
Why water tanks in tall buildings are placed at the top of the building?
Tall buildings are found in well developed urban areas, where civic infrastructure is in place that includes water supply to buildings. This water that is sent to buildings comes from treatment plants that ensure the water is clean and safe for drinking (potable). Once treated, the water is then pressurized in pipes that carry this water to the building. In most cities, the pressure level in these pipes provided by the city is somewhere around 50 pounds per square inch (psi).
When a tall building is constructed, this means many toilets, sinks, showers, and other plumbing fixtures are very high in the air. Once the pipes that carry water turn from horizontal to vertical to carry the water to upper floors, they must overcome the force of gravity. The force on the ground of 50 psi can only elevate the water inside the pipe up to a height of about the 5th floor of the building - while still having enough pressure left to run the fixture. Thus, floors higher than this must get pressurized water some other way than merely relying on the pressure in the pipes from the city water supply.
There are many ways to achieve this. One way is to add pumps on the ground level that boost the water even higher. The problem with doing this (and only this) is that if several people on several floors all use plumbing fixtures at once, there will not be enough water pressure. To prevent this from happening, storage tanks are placed high up in the air and these tanks are filled with water throughout the day (even when no fixtures are used). From the storage tank, pipes carry water downward, with the force of gravity, to the fixture. By having this stored water high in the air, many people can use plumbing fixtures all at once, and there is plenty of pressure from the water overhead to meet this demand.
As the variables are independent, we can combine them every way we want to, so:
6*6*2 = 72 alternative home designs.
What is technical difference between fire and non fire rated steel doors?
Fire rated doors comply with certain standards (NFPA 80) and building codes so that the door functions to reduce the spread of fire and smoke.
A crack in buildings is generally referred to a line which separates two segments of a building. It is detrimental to the quality of the building, and causes a loss of strength in the structure and support of the building.
Expansion joints are used in bridges in order to prevent the bridge from?
Buckling; shriveling, bending, or curling from heating or pressure. (heating, in this case)
Are they rebuilding the Twin Towers?
No, the Twin Towers will not be rebuilt. Instead, a new tower (a single tower) will be built in their place. It will be called Freedom Tower. It will be completed in 2013. Construction is well underway.
What kind of room isn't in a house?
There are several options: a garage, an outhouse, a board room, etc. However, I suspect this is actually a riddle.
Is The World Trade Center going to be the worlds tallest building in the world?
No, but it will be the tallest in America until the Chicago Spire is Topped out.
What makes the Eiffel tower strong and stable?
The Eiffel is very stable because Gustave Alexandre Eiffel who built it used many well thought out structural members to support the body and shape of the iron tower!!!
I honestly do not know, but having passed there many times,one I am so impressed by the Granduer and two I am so curious who lives there and the History, wouldnt want to be the brickie!
What geometric shapes are in the Eiffel Tower?
Eiffel Tower contains geometric shapes such as squares and vertical triangles.
What do you call the landing above the basement entrance to a brownstone building?
They used to call it the Stoop
What was the major building material on the great plains?
The major building material on the Great Plains was wood. Entire trees were cut down and the logs were used to build houses. The logs were lined up and stacked with mortar in between. There were usually no windows but boards that were hinged to the log house. The roofs were made of sod.
Are there foundations in Sri Lankan homes?
Yes of course. Especially the houses in Colombo. The local construction industry has been among the most respected in South Asia after it became a republic in 1972 and the development was lead by Pioneer construction magnate U.N. Gunasekera and maintained by the likes of Tudawe brothers, L.H. Piyasena and is now lead by companies such as MAGA and Sierra.
What shape has best section modulus?
The answer depends of the forces applied to the beam:
- for a single-directional force, the answer is a hollow rectangular shape (with the force applied on the narrow face); an I-beam is the second best.
- For forces applied in two perpendicular directions, the answer is a hollow square section.
- For forces applied from any direction, the answer is a hollow circular bar - a pipe.
