In this respect, two software programs, based on time history analysis, have been specially created to ensure the best possible protection through the optimization of the force-displacement characteristics of the energy absorbing devices.
No matter what type of structure, bridge or viaduct, JARRET has created shock absorbers which dissipate a large part of the kinetic energy, reducing the displacement of the deck and minimizing the forces on the abutments and supporting columns.
JARRET devices are easily adapted to meet the requirements of different types of structures :
- As an energy dissipation device in a base isolation system
- The reduction of inter-story drift for flexible structures
