. Typical structures designed by a structural engineer include buildings, towers, stadiums, 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

Fatigue is also an important consideration for bridges and aircraft design or for other structures that experience many stress cycles over their lifetimes. Consideration is also given to the 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

Recently in the United States, there have been discussions in the structural engineering community about the knowledge base of structural engineering graduates.

Licensing or chartered status

In the United States, persons practicing structural engineering must be licensed in each state in which they practice. Licensure may usually be obtained by the same qualifications as for a Civil Engineer, but some states require licensure specifically for structural engineering, with experience specific and non-concurrent with experience claimed for another engineering profession. 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 Engineering and Surveying The National Council of Examiners for Engineering and Surveying (NCEES) is an American non-profit organization dedicated to advancing professional licensure for engineers and surveyors. The Council’s members are the engineering and surveying lic ...

portion. Most states do not have a separate structural engineering license. In Alaska, California, Hawaii, Illinois, Nevada, Oregon, Utah, and Washington, there is 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 Alaska, California, Nevada, Oregon, Utah, and Washington and is reserved entirely to S.E. licensees in Hawaii and Illinois.

Legally it is not necessary to be a member of the IStructE when working on structures in the UK, however, industry practice, insurance, and liabilities dictate that an appropriately qualified engineer be responsible for such work. In the United States, application for license exam is allowed four years after the candidate graduated from an ABET-accredited university and passing the fundamentals of Engineering exam, three years after receiving a master's degree, or two years after receiving a Ph.D. degree.
