Abstract: This study focuses on the eigenfrequency determination of a cracked reinforced concrete beam.
In a first step, the influence of the steel rebars inside the concrete beam is studied and an analytical approach is proposed for the modeling of a cracked beam with composite strengthening.
An experimental validation is carried out on small-scale reinforced concrete beam.
In a second step, a prevision of the cracking pattern is implemented in the modeling so as to predict the natural frequencies of a beam as a function of the maximal moment which was applied to the beam.
This is experimentally validated with small-scale models and it is shown how that may be used to assess the damage of a beam.
