Damage location in steel-concrete composite beams using energy transfer ratio (ETR)

Tomasz Wróblewski, Małgorzata Jarosińska, Stefan Berczyński
The paper suggests a method of how to locate damage in steel-concrete beams using the energy transfer ratio (ETR). The initial numerical analyses performed for a simple model with 12 degrees of freedom confirmed the effectiveness of using the method for locating changes taking place in a structure. Successive analyses were conducted for a composite beam whose numerical model was developed in convention of the rigid finite element method RFE. Damage was introduced into the model, which was later localized on the basis of changes in the ETR.
