This sub-discipline of civil engineering focuses on structural Design and analysis of buildings, foundations and Supports, Bridges, towers, etc. The work involves identifying the loads Which Act upon a structure, analyzing the forces and stresses Which arise due to those loads, and then designing the Structure to successfully handle the loads. Design Considerations include strength and stability of the Structures when subjected to static loads such as self-weight And dynamic loads such as wind, seismic. Construction, etc. Engineering designs take into account cost, constructability, Safety, aesthetics and sustainability. Individuals might find Themselves designing special concrete industry Buildings, Equipment, generators, fans, compressors, pumps, Exchangers, Petrochemical and transmission towers, large rotating Equipment, vessels; or, designing buildings, pipe racks, Pipe bridges, platforms, walkways, equipment supports, Transmission towers and flare stacks, using structural steel.
