Abstract (EN): One of the concepts for damage detection in bridge structures, supported by monitoring techniques, involves the comparison of the structure¿s response obtained in the monitoring stage with that of a baseline condition. For a successful application of this concept, the reasons which might lead to a modification of the structure response have to be understood. In this context, the present paper discusses the relevance of the in-service nonlinear behaviour of structures which are compressed (thanks to the prestress action) but exhibit some cracking (due to actions applied during construction, extreme load events, or other causes). This study is based on the laboratorial testing of a prestressed concrete frame subjected to a moving load. The interpretation of the measured values is supported by finite element analyses considering the structure nonlinear behaviour and the supports deformability. © 2016 Taylor & Francis Group, London.
