Predicting the service life of buildings and components

摘要: The prediction of the service life buildings and engineered structures is complex. Such predictions are usually carried out on a component-by-component basis, but must incorporate variations in component design, material type, usage environment. Extensive databases required to cover vast number components/environments/usage combinations that exist or structures. This study investigated diverse methods used model components structures, including data mining maintenance records, expert opinion surveys (Delphi surveys), multiscale process modelling, sensing. These were analysed terms issues identified above their applicability meet differing uses data. Detailed case studies presented strengths weaknesses with respect final prediction.
