What is Rienforcedment Concrete?

 



Reinforced concrete, Concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. Plain concrete does not easily withstand tensile and shear stresses caused by wind, earthquakes, vibrations, and other forces and is therefore unsuitable in most structural applications. In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans. The invention of reinforced concrete in the 19th century revolutionized the construction industry, and concrete became one of the world’s most common building materials.

What Does a Structural Engineer Do?

Structural engineering is a branch of civil engineering, and its applications are diverse. A great deal of what structural engineers do involves designing structures such as buildings, bridges, tunnels, etc. The majority of structural engineers work primarily as consultants to architects or design-build contractors. The architect or design-builder comes up with a building layout, and then it's the structural engineer's responsibility to calculate the loads (such as snow, wind and earthquake forces), fit the structure to the architecture, and decide on what structural systems to use. The structural systems include steel, concrete, masonry, wood and other materials from which the engineer selects beams, columns, and other members that make up the building support. If one considers the human body as analogous to a building, structural engineers would be the professionals that design the skeleton so that the body can support its weight and other forces that act on it.
Though structural engineers generally are involved with the design of new buildings, they are sometimes involved in the demolition or dismantling of a structure, either permanently or in order to repair it. They also inspect structures both during and after construction to ensure that they are properly constructed.
Because the work of structural engineers is closely tied to public safety, they must be registered with the state in which the practice in order to demonstrate their abilities. Generally speaking, a registered engineer has at a minimum a bachelor's degree in engineering and at least four years of experience working under the supervision of a registered engineer. After obtaining these credentials the engineer must pass a licensing exam and after passing the exam the engineer can then practice as a registered engineer.

What is Structural Enigneering mean?

 

Structural Engineering is concerned with the research, planning, design, construction, inspection, monitoring, maintenance, rehabilitation and demolition of permanent and temporary structures, as well as structural systems and their components. It also considers the technical, economic, environmental, aesthetic and social aspects of structures.
Structures can include buildings, bridges, in-ground structures, footings, frameworks and space frames, including those for motor vehicles, space vehicles, ships, aeroplanes and cranes. They can be composed of any structural material including composites and novel materials.
Structural engineering is a creative profession that makes a significant contribution to infrastructure, industry, as well as residential and recreational developments.
Structural engineers carry out strength calculations and prepare drawings of structures to ensure they are strong enough to avoid collapse when loaded. The most common structures dealt with are buildings and bridges, but tunnels, walls to hold back earth embankments, large tanks and silos as well as mining structures, also form part of a structural engineer's work. Specialist areas include oil drilling platforms and associated infrastructure, shipbuilding and aircraft design.
Structural engineers generally work in teams and look at the way a structure is to be built. They ensure buildings are strong enough to withstand natural forces and loads imposed by the nature of its use. Through research and the testing of both form and material, new solutions are developed which promote safer, more environmentally friendly buildings and structures.
Some structural engineers work in the design of structures (carrying out the strength calculations and supervising drawings), others specialise in the building of structures and some work in research. Structural engineers commonly work with architects, builders, mechanical, electrical and chemical engineers to ensure that all parts of the structure are safe and capable of fulfilling their intended function. They also make sure structures use appropriate materials efficiently.

What is Civil Engineer

Civil engineering is arguably the oldest engineering discipline. It deals with the built environment and can be dated to the first time someone placed a roof over his or her head or laid a tree trunk across a river to make it easier to get across.
The built environment encompasses much of what defines modern civilization. Buildings and bridges are often the first constructions that come to mind, as they are the most conspicuous creations of structural engineering, one of civil engineering's major sub-disciplines. Roads, railroads, subway systems, and airports are designed by transportation engineers, another category of civil engineering. And then there are the less visible creations of civil engineers. Every time you open a water faucet, you expect water to come out, without thinking that civil engineers made it possible. New York City has one of the world’s most impressive water supply systems, receiving billions of gallons of high-quality water from the Catskills over one hundred miles away. Similarly, not many people seem to worry about what happens to the water after it has served its purposes. The old civil engineering discipline of sanitary engineering has evolved into modern environmental engineering of such significance that most academic departments have changed their names to civil and environmental engineering.
These few examples illustrate that civil engineers do a lot more than design buildings and bridges. They can be found in the aerospace industry, designing jetliners and space stations; in the automotive industry, perfecting the load-carrying capacity of a chassis and improving the crashworthiness of bumpers and doors; and they can be found in the ship building industry, the power industry, and many other industries wherever constructed facilities are involved. And they plan and oversee the construction of these facilities as construction managers.
Civil engineering is an exciting profession because at the end of the day you can see the results of your work, whether this is a completed bridge, a high-rise building, a subway station, or a hydroelectric dam.
