Application of Meta-Modeling for Quality Assurance of Automated High Fidelity Bridge Structure Models

Abstract

 We propose quality assurance procedures of automatically constructed models for seismic response analysis. In these procedures, models of different fidelity are used, and the quality of a higher fidelity model is examined by comparing its response with a lower fidelity model. A key issue is the consistency of the models of different fidelity, and the meta-modeling theory is used to guarantee the consistency. As an illustrative example, models of different fidelity are automatically constructed for a bridge structure, and it is shown that the developed procedures are applicable to them. The quality of the automated solid element model that is of highest fidelity is examined.
