Ethics in Engineering Practice and Research

“A STRUCTURAL ENGINEER”

Structural Engineering is a specialty within Civil Engineering. Structural Engineers create drawings and specifications, perform calculations, review the work of other engineers, write reports and evaluations, and observe construction sites. A Professional Engineer’s license is required in order to practice Structural Engineering. A license can be obtained only after completing a prescribed amount of education and work experience, and taking a 2-day exam. In California and other states, certain structures, such as hospitals and schools, require a Structural Engineer’s license, which can be obtained after 3 years additional experience and taking another exam.

“ANALYZES AND DESIGNS”

The basic tasks of structural engineering relate numerical quantities of physical forces to physical configurations of force-resisting elements. Analysis is the process of determining forces in each element in a structure (such as a beam) when the configuration of elements is already defined. Design is the process of configuring elements to resist forces whose values are already known. Analysis and Design are complementary procedures in the overall process of designing new structures. After performing a preliminary design, the designer estimates the final configuration of elements of a structure, but only until an analysis is performed can the forces in those elements be known. After performing an analysis, the element forces are known, and the elements can be designed (their configuration can be chosen) more precisely. The process iterates between analysis and design until convergence is achieved.
