SHORT INTRODUCTION OF STRUCTURAL ENGINEERING.
Have you
ever wondered how a cruise liner or cruise ships, like the queen Elizabeth; a
jumbo jet or queen of sky, like the A360; a big bridge like THE Rio–Niterói
Bridge in Brazil, the Great Seto Bridge in japan, the Maputo–Katembe bridge in Moçambique,
the Vasco da Gama Bridge
in Portugal, Danyang–Kunshan Grand
Bridge in China, The golden gate in San
Francisco, or a skyscraper like the hotel Burj Al Arab, a Burj Khalifa in Dubai
and the Shard in London, stand tall?

Structural engineering is a specialized
branch of civil engineering.
Everything has structure. The
function of structure is to provide the form and shape on which other functions
can operate. Natural structures vary from the very smallest part of an atom to
the entire cosmology of the universe. Man-made structures include buildings,
bridges, dams, ships, aeroplanes, rockets, trains, cars, and fairground rides,
and all forms of artefacts-even large sculptures like the Angel of the North in
UK.
Structure is the difference between a random pile of
components and a fully functional object. Through structure, the parts connect
to make a whole.
Engineering is the turning of ideas into
reality. Structural engineering is acritical part of the fulfilling of some of
our most basic human needs – particulary for shelter, protection and travel. It
has evolved from the common-sense building and primitive huts, bridges, and
weapons of ancient history, through the craft skills of medieval master masons
who built castles, cathedrals, and country houses, to the latest and most
sophisticated use of the science of structure and materials.
The wide range of different industries in
which structural engineers work includes construction, transport,
manufacturing, and aerospace. Each industry has its own particular ways of
doing things.
The work in a typical structural engineering
design consultancy might be:
·
30% on
design discussions;
·
30% on
structural analysis;
·
30% on
determining construction details;
·
And 10%
on specifying, supervising, and checking the work.
The
high proportion of structures engineer´s work consists of structure
analysis - the application of the tools of mathematics to
determine forces stresses and strains in the structures that he is called upon
to design. The accurate and economic design of structures usually requires the
use of a variety of formulae and considerable calculation. For some structures,
the mathematics involved may be simple, but for others it can be of an advanced
standard, involving laborious calculation. For many complex structures,
electronic computers are being increasingly used.
Another
important tool is a sound knowledge of the nature, properties and behavior of
the structure materials.
The
chief structure materials are brick, stone, concrete, timber and steel. In
recent years, aluminum alloys have been used for some types of structure, and
even some plastics have been used structurally.
So,
this a brief introduction of structural engineering. Just leave comments if you
