Structural engineering Wikipedia. The Eiffel Tower in Paris is a historical achievement of structural engineering. Cisco Asa License Key Generator. Structural engineering is a sub discipline of civil engineering in which structural engineers are trained to understand, predict, and calculate the stability, strength and rigidity of built structures for buildings1 and nonbuilding structures, to develop designs and integrate their design with that of other designers, and to supervise construction of projects on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. Structural engineering theory is based upon applied physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design utilizes a number of relatively simple structural elements to build complex structural systems. Structural engineers are responsible for making creative and efficient use of funds, structural elements and materials to achieve these goals. Structural engineer professionaleditStructural engineers are responsible for engineering design and structural analysis. Entry level structural engineers may design the individual structural elements of a structure, such as the beams and columns of a building. More experienced engineers may be responsible for the structural design and integrity of an entire system, such as a building. Structural engineers often specialize in particular types of structures, such as buildings, bridges, pipelines, industrial, tunnels, vehicles, ships, aircraft and spacecraft. Structural engineers who specialize in buildings often specialize in particular construction materials such as concrete, steel, wood, masonry, alloys and composites, and may focus on particular types of buildings such as offices, schools, hospitals, residential, and so forth. Structural engineering has existed since humans first started to construct their own structures. It became a more defined and formalized profession with the emergence of the architecture as distinct profession from the engineering during the industrial revolution in the late 1. Until then, the architect and the structural engineer were usually one and the same thing the master builder. Only with the development of specialized knowledge of structural theories that emerged during the 1. The role of a structural engineer today involves a significant understanding of both static and dynamic loading, and the structures that are available to resist them. The complexity of modern structures often requires a great deal of creativity from the engineer in order to ensure the structures support and resist the loads they are subjected to. A structural engineer will typically have a four or five year undergraduate degree, followed by a minimum of three years of professional practice before being considered fully qualified. Structural engineers are licensed or accredited by different learned societies and regulatory bodies around the world for example, the Institution of Structural Engineers in the UK. Depending on the degree course they have studied andor the jurisdiction they are seeking licensure in, they may be accredited or licensed as just structural engineers, or as civil engineers, or as both civil and structural engineers. Another international organisation is IABSEInternational Association for Bridge and Structural Engineering. The aim of that association is to exchange knowledge and to advance the practice of structural engineering worldwide in the service of the profession and society. History of structural engineeringeditStructural engineering dates back to 2. B. C. E. when the step pyramid for Pharaoh Djoser was built by Imhotep, the first engineer in history known by name. Pyramids were the most common major structures built by ancient civilizations because the structural form of a pyramid is inherently stable and can be almost infinitely scaled as opposed to most other structural forms, which cannot be linearly increased in size in proportion to increased loads. The structural stability of the pyramid, whilst primarily gained from its shape, relies also on the strength of the stone from which it is constructed, and its ability to support the weight of the stone above it. The limestone blocks were often taken from a quarry near the build site and have a compressive strength from 3. MPa MPa Pa 1. Therefore, the structural strength of the pyramid stems from the material properties of the stones from which it was built rather than the pyramids geometry. Throughout ancient and medieval history most architectural design and construction was carried out by artisans, such as stone masonrymasons and carpenters, rising to the role of master builder. No theory of structures existed, and understanding of how structures stood up was extremely limited, and based almost entirely on empirical evidence of what had worked before. Knowledge was retained by guilds and seldom supplanted by advances.

No record exists of the first calculations of the strength of structural members or the behavior of structural material, but the profession of structural engineer only really took shape with the Industrial Revolution and the re invention of concrete see History of Concrete. The physical sciences underlying structural engineering began to be understood in the Renaissance and have since developed into computer based applications pioneered in the 1. Timelineedit1. 82. Claude Louis Navier published a treatise on the elastic behaviors of structures. Carlo Alberto Castigliano presented his dissertation Intorno ai sistemi elastici, which contains his theorem for computing displacement as partial derivative of the strain energy. This theorem includes the method of least work as a special case.

Structural failureeditThe history of structural engineering contains many collapses and failures. Sometimes this is due to obvious negligence, as in the case of the Ption Ville school collapse, in which Rev. Fortin Augustin constructed the building all by himself, saying he didnt need an engineer as he had good knowledge of construction following a partial collapse of the three story schoolhouse that sent neighbors fleeing. The final collapse killed 9. In other cases structural failures require careful study, and the results of these inquiries have resulted in improved practices and greater understanding of the science of structural engineering. Some such studies are the result of forensic engineering investigations where the original engineer seems to have done everything in accordance with the state of the profession and acceptable practice yet a failure still eventuated.
