Aging and dynamic behaviour of a bridge
Aging consequences (micro cracking) on the dynamic behaviour of a rail bridge
Assessment of the dynamic behaviour of a pre-cracked (aging consequence) reinforced concrete bridge when crossed by a high speed train. Dynamic non linear time history analysis. Effects of the ballast on the dynamic behaviour.
Design studies of vibration and slow strain sensitive structures
Golden Slab of the ESRF synchrotron - EX2 project (particle accelerator)
Design studies of test slabs. Preliminary assessment of the technical solutions for the foundations, monitoring of the structure behaviour during construction, and validation by in situ measures. Stability of the slab to thermal variations, concrete shrinkage, dynamic loads applied on the slabs. Organisation of data collection programs, and validation of numeric modelling.
