The structural elements guiding the systemic forces through the materials are not only such as a connecting rod, a truss, a beam, or a column, but also a cable, an arch, a cavity or channel, and even an angle, a surface structure, or a frame. It is important for a structural engineer to be able to classify a structure by either its form or its function, by recognizing the various elements composing that structure. Other branches of engineering work on a wide variety of non-building structures.Ī structural system is the combination of structural elements and their materials. To design a structure, an engineer must account for its safety, aesthetics, and serviceability, while considering economic and environmental constraints. Important examples related to Civil Engineering include buildings, bridges, and towers and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important.
