''Structural engineering'' is concerned with the [[structural design]] and [[structural analysis]] of buildings, bridges, [[tower]]s, [[overpass|flyovers]] (overpasses), tunnels, off shore structures like oil and gas fields in the sea, [[aerostructure]] and other structures. This involves identifying the loads which act upon a structure and the forces and stresses which arise within that structure due to those loads, and then designing the structure to successfully support and resist those loads. The loads can be self weight of the structures, other dead load, live loads, moving (wheel) load, wind load, earthquake load, load from temperature change etc. The structural engineer must design structures to be safe for their users and to successfully fulfill the function they are designed for (to be ''serviceable''). Due to the nature of some loading conditions, sub-disciplines within structural engineering have emerged, including [[wind engineering]] and earthquake engineering.<ref>{{cite book |last1=Narayanan |first1=R |first2=A |last2=Beeby |title=Introduction to Design for Civil Engineers |location=London |publisher=Spon |date=2003}}</ref>

Design considerations will include strength, stiffness, and stability of the structure when subjected to loads which may be static, such as furniture or self-weight, or dynamic, such as wind, seismic, crowd or vehicle loads, or transitory, such as temporary construction loads or impact. Other considerations include cost, constructibility, safety, aesthetics and [[sustainability]].
