Abstract

The deformation of buildings or constructions e.g. caused by climatic or seismic forces is controlled by cross bracing the structure. At each end of the cross bracing strut are tension or compression compensating units. Each unit has a support body with features allowing it to be fastened to the node of the structure. - The unit is attached to its cross bracing by bolts which slide in slots on low friction washers or spacers. The tension or compression loads are absorbed and counteracted by a pile of elastic elements e.g. springs, Belleville washers, rubber blocks etc. with an elasticity to suit each application. External tie bars compress the elastic elements during installation.

- An isostatic lattice frame, see fig II, ave & diagonal equipped with the stabilizing device placed at the ends undergoes a first deformation, see fig III, without alteration of the lengths of the uprights and of the frame crosspieces.

  
The theoretical length of the diagonal increases.

  
Compensators It double effect It equips this stabilizing device, see B 1.04 - COMPOSITION.

  
The device is fixed to the ends of the diagonal but can slide, thus ensuring the variation of the theoretical length of this diagonal without altering its length
