A Meta Model for Damage Prognosis of Concrete Structure

摘要

Deterioration of concrete structures is a big problem; premature or unexpected failures of these structures are often catastrophic. Damage prognosis has become a new research focus that tries to use damage diagnosis knowledge to inform the responsible authorities on the expected remaining service life of the structure. The purpose of prognosis is to extract damage features from input-output or output-only data and model damage evolution to predict the remaining life of the structure. In this paper, we are presenting a reduced order model (Meta model) prototype for damage prognosis of concrete structure, which captures the relationship between inputs and outputs without providing a detailed description of the physics and geometry.
