A benchmark problem for structural health monitoring based on a real bridge structure

A benchmark study is a valid way to make comparison of kinds of Structural Health Monitoring technologies, for example modal identification, finite element model updating, damage identification and so on. Several successful benchmark SHM problems were developed by IASC-ASCE SHM Task Group and the encouraging analytical studies results were obtained. But this benchmark study is based on a steel-frame scale-model structure built in the laboratory. Due to the striking difference in structure’s properties, SHM system and so on between the structure in the laboratory and the real structure, many SHM technologies developed in the laboratory is not applicable to the real structure. Thus a new benchmark study based on a real structure is developed in this paper. The first and the second phase of a benchmark problem based on SHM system for Binzhou Yellow River Highway Bridge have been detailed and the criterion of benchmark problem are given simultaneously.
