Engineering investigation and determination of the causes of structural failures of buildings, bridges, and other constructed facilities, as well as rendering opinions and giving testimony in judicial proceedings, has become a field of professional practice of its own, often referred to as forensic structural engineering. Structural failure does not have to be a “catastrophic collapse,” it may be a “nonconformity with design expectations” or “deficient performance.” Collapse is usually attributed to inadequate strength and/or stability; deficient performance, or so-called serviceability problems, is usually the result of abnormal deterioration, excessive deformation, and signs of distress. In short, structural failure may be characterized as the unacceptable difference between intended and actual structural performance.
