# Steel Construction Part C – Quiz and Interview Questions

Structural design is a process by which a structure required to perform a given function is proportioned to satisfy certain performance criteria (size, shape, etc.) in a safe and economic way. To a large extent design is a pencil and paper exercise (electronic computation must also be included in the list of design tools), by which a mathematical model of the real structure is tested for adequate
performance.
