Résultats exploitables
The main achievements can be summarized as follows:
1. Long term monitoring and progressive damage tests on a full scale highway bridge (Z24 in Switzerland), additional tests on three bridges (on of them before and after repair). The tests on the Z24-bridge are recorded on videotape to promote the monitoring technology developed within the SIMCES-project. The data can be made available for validation of system identification algorithms and/or damage detection methods.
2. Dynamic tests on progressively damaged reinforced concrete (RC-) beams.
3. Guidelines for a proper monitoring setup.
4. Development of time domain system identification (SI-) methods using operational data only (ANPSD, LSCE, SSI, ARMAV).
5. Implementation of SI-methods in userfriendly software modules.
6. Comparison, between different SI-methods, between results obtained by forced (FVT) and ambient (AVT) vibration, by using the bridge data.
7. Statistical treatment of the long term data of the Z24-bridge. Critical appraisal of temperature influence.
8. Construction of numerical FE-models to simulate damage (cracking) in reinforced / prestressed concrete structures. Application to the tested bridges and the RC-beams.
9. Development of damage identification methods: (traditional) updating, direct stiffness calculation (DSC), design of experiments (DOE) / response surface model (RSM) approach.
10. Application of the damage identification methods to the Z24-bridge and the RC-beams.
