arret Structures devices are easily adapted to meet the
requirements of different types of structures :
- As an energy dissipation device in a base isolation system
- As a reducer of inter-story drift for flexible structures.
es dispositifs Jarret Structures s'adaptent aussi
efficacement aux différents concepts de construction :
- Protection par isolation à la base pour les structures rigides
- Protection inter-étage dans le cas de structures flexibles.
