Everything about Structural Engineer totally explained
A
structural engineer is an engineering professional who practices
structural engineering.
Structural engineers analyze, design, plan, and research
structural components and
structural systems. Their work takes account mainly of technical, economic and environmental concerns, but they may also consider aesthetic and social factors.
Structural engineering is usually considered a specialty discipline within
civil engineering, but it can also be studied in its own right. In the US, most practising structural engineers are currently licensed as
civil engineers, but the situation varies from state to state. In the UK, most structural engineers in the building industry are members of the
Institution of Structural Engineers rather than the
Institution of Civil Engineers.
Typical structures designed by a structural engineer include
buildings,
towers,
stadia and
bridges. Other structures such as
oil rigs, space
satellites,
aircraft and
ships may also be designed by a structural engineer. Most structural engineers are employed in the construction industry, however there are also structural engineers in the aerospace, automobile and shipbuilding industries. In the construction industry, they work closely with
architects, civil engineers,
mechanical engineers,
electrical engineers,
quantity surveyors, and
construction managers.
Structural engineers ensure that buildings and bridges are built to be strong enough and stable enough to resist all appropriate
structural loads (for example, gravity, wind, snow, rain, seismic (
earthquake), earth pressure, temperature, and traffic). They also design structures to be
stiff enough to not
deflect or
vibrate beyond acceptable limits.
Fatigue may be an important consideration for bridges and for aircraft design, or for other structures which experience a large number of stress cycles over their lifetime. Consideration is also given to durability of materials against possible deterioration which may impair performance over the design lifetime.
Education
The education of structural engineers is usually through a
civil engineering bachelor's degree, and often a master's degree specializing in structural engineering. The fundamental core subjects for structural engineering are
strength of materials or
solid mechanics,
statics,
dynamics,
material science,
numerical analysis and
conceptual structural design.
Reinforced concrete,
composite structure,
timber,
masonry and
structural steel designs are the general
structural design courses that will be introduced in the next level of the education of structural engineering. The
structural analysis courses which include
structural mechanics,
structural dynamics and
structural failure analyses are designed to build up the fundamental analysis skills and theories for structural engineering students. At the senior year level or in graduate programs,
prestressed concrete design,
space frame design for building and aircraft, bridge engineering, civil and aerospace structure rehabilitation and other advanced structural engineering specializations are usually introduced.
Recently in the United States, there have been discussions in the structural engineering community about the knowledge base of structural engineering graduates. Some have called for a master's degree to be the minimum standard for professional licensing as a civil engineer
(External Link
). There is a separate structural engineering undergraduate degree at the
University of California, San Diego. Many students who later become structural engineers major in civil, mechanical, or aerospace engineering degree programs, with emphasis in
structural engineering.
Architectural engineering programs do offer structural emphases, and are often in combined academic departments with civil engineering.
Licensing/Accreditation
In the United States, persons practicing structural engineering must be licensed in the state(s) in which they practice as a Civil Engineer. The qualifications for licensure typically include a specified minimum level of practicing experience, as well as the successful completion of a nationally administered exam, and possibly a state-specific exam. For instance, California requires that candidates pass a national exam, written by the National Council of Examiners for Engineers and Surveyors (NCEES) (http://www.ncees.org), as well as a state-specific exam which includes a
seismic portion and a
surveying portion. Most states don't have a separate structural engineering license. In California, Washington, Nevada and a few other states, there's an additional license or authority for Structural Engineering, obtained after the engineer has obtained a Civil Engineering license and practiced an additional amount of time with the Civil Engineering license. The scope of what may be designed by a Structural Engineer but not by a Civil Engineer without the S.E. license is very limited.
In the
United Kingdom, there's no licensing the way there's in the United States, but there are organizations which grant the title of
Chartered Engineer, and the Institution of Structural Engineers (IStructE) grants the title of
Chartered Structural Engineer. The overall process toward this qualification begins after graduation from a UK MEng degree, or a BEng with a MSc degree. To qualify as a chartered structural engineer, a graduate needs to go through four years
Initial Professional Development to prepare for their professional review interview. After passing the interview, the candidate is able to sit an eight hour professional review examination. The election to chartered membership (MIStructE) is depending on the examination result. The candidate can register at the
Engineering Council UK as a Chartered Structural Engineer once he or she's been elected as a Chartered Member. It isn't necessary to be a member of the IStructE (or any other body) to practice as a structural engineer in the UK.
