Civil Engineering

Impact test determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness and acts as a tool to study temperature-dependent brittle-ductile transition.

It is to determine whether the material is brittle or ductile in nature.

It can take up to at least five years to build a hydroelectric dam.

It all depends on the dimensions of the steel beam

because it is the supreme elemnt of the structure.and all the loads can bear it so that's y we take strength reduction factor is less

A shallow foundation is generally considered any foundation element that is 6 feet or less in depth. or the depth of foundation is equals to its width of the foundation. Examples are thickened edge slabs and grade beams that are supporting minimal weight.

The longest span an arch bridge can go is relevent to the radius of the arch.

Singly reinforced beams have reinforcing only on the tension face. Doubly reinforced beams have reinforcing on the tension and compression face. Doubly reinforced beams can increase section capacity, but are primarily used to increase the ductility of the concrete beam. In certain codes, if the concrete section is controlled by the concrete failing in compression before the tension steel rebar yields (called a compression-controlled or brittle section), the calculated section capacity must be reduced to account for the brittle and sudden/unpredictable nature of a compression controlled (also called a brittle) failure. In order to make the section controlled by the yielding of the tension reinforcement (called a tension-controlled or ductile section), the ductility must be increased. This can be accomplished by adding steel in the compression zone, which gives strength to the compression area, thereby delaying the failure of the concrete. Enough compression steel can cause the section to switch from a brittle mode-of-failure to a ductile mode-of-failure, thereby permitting the designer to not decrease the section capacity from its calculated value.

When identifying a doubly- reinforced beam, be sure that the steel in the compression area is meant to be for strength. Oftentimes, all faces of a beam will have some reinforcing for temperature/shrinkage protection and to tie the stirrups to. Steel that is only there for temp/shrinkage or to facilitate tying the rebar will usually be small and not much of it. In buildings, they will be often #3 bars @ 12" centers. In bridges, they may be #4 bars. These small bars should not be counted as compression-zone reinforcing. Look for bars in the compression zone that are of similar size to the main tension reinforcing.

A bridge is a way to connect two networks. For example, if a user has two or more computers connected to a wired network, and one of those wired computers is connected to a wireless network, the computer connected to both the wired and wireless networks could be used as a bridge. With the bridged networks, the wired computers could access the wireless network.

Because all construction takes place in or on the ground, geotechnical engineering plays a crucial role in all civil engineering projects. The need to investigate the ground is of vital importance before any construction work takes place. The failure to carry out adequate site investigations often has had dramatic and expensive consequences on construction projects. Geotechnical engineers require a wide variety of skills and, in general, need to be smarter than other kinds of engineer. Whereas most engineers have the luxury of specifying the materials they use, the geotechnical engineer has no choice but to work with the natural soil and rock as he or she finds it. In a geotechnical consulting firm, everyone works in a team to complete a project. A team usually comprises a project director who oversees the whole project; a senior engineer, assisted by one or more engineers and geologists; a checker or checkers to make sure everything is done correctly; followed by an internal and an external reviewer.

( A bridge was designed as a vertical curve above a train line according to the gradients (g 1 =+3.6%g g 2 =-2.9%) , if you know that the designed length of the bridge equal to 530 m find the following : a) Rate of change in gradient for each station . b) Elevation and station for each of intersection and end points if you know that the elevation and station of start point are 34.5 m and 23 + 00 respectively . c) Check if the design is ok if you know that the level of train line is 35.00 m and the minimum allowable height of the bridge at mid -point is 5.2 m

I guess it's the strongest form of structure to form the end of the upright cylinder which is the basic reactor enclosure. The reactor must be enclosed with a structure which can contain the worst type of reactor failure which would release a lot of steam. It also protects the reactor and its equipment from the weather.

The nasal bones make up the bridge of your nose. There are two small oblong bones, varying in size and form in different individuals; they are placed side by side at the middle and upper part of the face, and form, by their junction, "the bridge" of the nose.

It is a measure of volume usually used when measuring the water in a lake or large reservoir. An acre foot is the amount of water that it would take to cover one acre of land with one foot of water.

The average salary of an environmental engineer is 83,000 dollars per year. The entry level positions usually pay around 62,000 dollars per year.

In the UK, you need a degree to become a Civil Engineer. This can be in the form of a four year MEng, or a three year BEng. To become Chartered (The professional recognition) you must undertake 3+ years of professional development and then take a test with the ICE. Professional development is a wide ranging term including, documenting the work you have performed showing a range of skills. This depends on the type of job you have, i.e. Consultancy or Contracting.

Generally 4 to 5 years of study at a college or university with an Engineering program, which includes a lot of math and sciences courses and many labs. You would most likely have to complete internships and co-op programs to inhance your learning. its simple but hectic. its also involves some design work and administration skills. all you need is to go and consult a university for the academia.. and the rest is upto you. its a responsible job. as it relates with lives. do take this study seriously or leave it. i am also a civil engineer! so trust me! Your first year will be general maths and physics, maybe a computer programming course, and most likely Drafting and/or Surveying. Second and third years you will take more maths courses, and you'll start courses in "structural analysis" (e.g. finding forces in the different members of frames and trusses). More complicated structures require more complicated analysis methods, which is why you took all that funky math in 1st & 2nd years! You will also start to get some courses in the properties of different materials (wood, steel, concrete) and how they behave under load. Likely there will be a lab or two on the subject, and these are usually quite fun. At this point you will also get some "Introduction to Design" courses where you start to match up the "Analysis" courses (finding loads and forces) with the properties of load carrying materials. In fourth year you will do specific courses in Steel Design, Concrete Design, maybe Wood Design, introducing you to the codes and standards required by law. There will likely also be courses in Construction Management and Ethics. If you have a choice, choose a co-op program: a lot of things like cost estimating and spec writing that you need as an engineer are not taught well or even at all in school. You will see them only on the job, and the sooner the better. Everyone knows that, of course, which is why you require a few years of work experience before you write the exams for your Province or State Licensing body to become a fully licensed Professional Engineer. It is a very rewarding profession---good luck with your studies!

The beautiful Golden Gate Bridge is the large suspension bridge located in San Francisco, spanning the gateway between the opening of the San Francisco Bay and the Pacific Ocean. The length of the bridge from abutment to abutment is 1.7 miles, the width is 97 feet and the bridge weighs around about 887 thousand tons including anchorages and approaches. The bridge is painted Orange Vermillion, also known as International Orange, and needs constant touch ups to make sure the salt content in the air does not erode it. When the Golden Gate Bridge was completed in 1937, it was the longest suspension bridge in the world. It is now the 2nd longest suspension bridge in the United States and the world's 9th longest suspension bridge.

Dams must hold back water of a certain depth, determined by the height of the dam. The pressure exerted by this water on the dam is dependent in part by its depth, since the base of the dam must be able to hold pressures exerted by the weight of all the water above the base. Since the pressure is greater at the base, the dam is broader at the base.

An overhanging beam is one that extends beyond its supports. This is also called a cantilever.

Some basic questions and answers in civil engineering include what it is. It is professional engineering dealing with design, construction, and maintenance of physically built works including bridges, roads, and buildings. How long does a civil engineer have to go to school? To get an academic degree in civil engineering, you need three to five years to complete your studies.

The answer will depend on how much there is.

First of all i guess the right question is difference between strain and deformation. Actually the strain is deformation in a material over its original length. So strain is a relative quantity while deformation is simply change in length, hence absolute and is new length minus original length.

Strain= deformation(L2-L1)/original length(L1)

As a prefix, it modifies an adjective to give the sense of extremeness: Absolute Zero is hyper-cold.

As slang, it's a short form of "hyperactive"; i.e. wound up and moving a lot, usually due to some medical condition.
