Abstract: The deflection of a bridge under a dominant load, called key deflection is an important parameter that reflects the load-bearing capacity of in-service bridges. The impact vibration test is a good candidate for obtaining ...

Abstract: Flexibility is a key parameter that reflects the service status of an engineering structure, which includes safety and applicability. Rapid structural safety evaluation based on active excitation tests for flexibility has ...

Abstract: To achieve a high-efficiency impact test for deck flexibility identification of bridges, a reference-free substructuring test strategy with a two-stage integration method is proposed, which can be adopted to integrate the ...

Abstract: A mode expansion method combined with a sparse point impact test strategy that establishes the relationship between the sparse flexibility matrix and the static response field of a bridge under a distributed load is proposed ...

Abstract: Flexibility plays an important role in bridge load-carrying capacity assessment. The flexibility of bridges has been extracted from the measured data of numerical impact testing and in laboratory experiments. Recently, ...
