Structural Engineering , is the application of physics for static loading. Slowly applied loadings are Static in nature. Therefore, requires investigation of Gravity(Dead) and Transient Loads(Live). Live loads are treated as pseudo-static in their application. By comparison, transient loads, in reality, are time-dependent e.g. require the solution of a differential equation. Therefore, simple structures are designed by static and pseudo-static loadings. Complex structures are designed for static and dynamic loads to add more economical member sizes and design for more realistic loading that a structure would see through its life,
Another definition that a working associate had on his wall is very fitting;
Structural Engineering, A discipline of how to design structures (we can’t precisely analyze!), which are subjected to different loads (we can’t exactly predict!), utilizing a variety of materials (we don’t fully understand!) in such a way that the general public does not realize the level of our ignorance.

- Structures are what transfer loads to the ground for our homes and office buildings, bridges, dams, electrical towers are some of those in the civil engineering field. In mechanical engineering structure and mechanism types such as cars, ships, airplanes, and rockets. Therefore, static loading conditions are investigated civil structures and are checked for dynamic loads e.g. seismic, wind, blast loading, to name a few. By comparison, mechanical structures are designed for dynamic loads and thermal forces; e.g. rockets are subjected to shock loading are well as large temperature fluctuations, airplanes must resist pressures generated by lift, drag, sonic and thermal forces.
