Shock transmission units
RESTON-STU
Seismic devices
Characteristics
Also know as lock-up devices
Form rigid connection when loaded by sudden strong dynamic actions
Free moving under service condition
Typically used for earthquake protection or braking forces
Principle
mageba RESTON-STU Shock Transmission Units are used to rigidly connect parts of a structure together under the action of sudden high dynamic loading (e.g. from an earthquake or from the braking of a train or a heavy road vehicle). However, they permit free movement due to slow-acting influences such as temperature changes or shrinkage and creep.
Applications
RESTON-STU Shock Transmission Units can be used in the construction of new structures, or to enhance an existing structure’s strength and resistance to seismic forces. On bridges, they are installed in the vicinity of bearings and expansion joints.
