Structural Identification of Constructed Systems: Approaches, Methods, and Technologies for Effective Practice of St-Id - Softcover

Inhaltsangabe

Structural Identification of Constructed Systems: Approaches, Methods, and Technologies for Effective Practice of St-Id offers an overview of nearly 20 years of research directed at bridging the gap in structural engineering between models and real structural systems. Structural identification, known as St-Id, can be defined as the process of creating and updating a model of a structure (for instance, a finite element model) using experimental observations and data. By developing reliable estimates of the performance and vulnerability of structural systems, St-Id produces improved simulations that, in turn, assist in decision making and the transition to performance-based civil engineering.

Drawing upon contributions from experts in the field, this report focuses on defining the most critical considerations of St-Id, which include:

• modelling, both analytical and numerical
• experimentation, including observations, sensing, and monitoring
• data processing, including error screening and feature extraction
• model calibration, including comparisons of models and experimental data, model updating, and model selection
• decision support, such as scenario analyses and risk assessment
• Two appendixes present case studies demonstrating the St-Id of buildings and of bridges.
