DESIGN OF REINFORCED CONCRETE SPECIMEN INTENDED FOR HYBRID TESTING
In the context of a collaborative project financed by ANR including ENS CACHAN, IFSTTAS, CEA, aiming at studying the dynamic behavior of structures reinforced by different technics, CES used its skills to contribute to the conception and atypical design of specimens.
One of the objectives of CEA was to include the presence of soil in the control strategy that is to say soil-structure interaction phenomena thanks to hybrid testing.

Cluster 32 cores – 64 Gb – CES
CES has developed its own computational tools in order to perform requested analyses
Within the framework of this innovative project, CES had to design steel and reinforced concrete specimens. Despite simple structural components, the testing devices on the shaking table brought about difficulties. That’s why CES performed a sensitivity analysis in order to define the formwork geometry before designing test specimens and detailed drawings.
