摘要:
La présente invention concerne un système amortisseur de choc pour véhicule automobile comprenant une cellule principale (100) adaptée pour être déformée en cas de choc d'un premier niveau d'énergie et une cellule secondaire (200) de plus faible longueur que la cellule principale (100), adaptée pour être sollicitée en complément de la cellule principale (100), après une première phase de déformation de la cellule principale (100), lorsque le système reçoit un choc d'un deuxième niveau d'énergie supérieur au premier, la cellule secondaire (200) étant configurée pour orienter la résultante d'application d'un effort sur une structure avale (30) dans une direction non parallèle à l'axe longitudinal de cette structure avale.
摘要:
A building structure including a plurality of vertical elements extending from a ground surface with at least a first of the vertical elements connected to a second of the vertical elements by a coupling member, the coupling member includes a damping element for damping vibrations in the building structure resulting from relative movement between the first and second vertical elements due to lateral loads applied to the building structure. The damping element undergoes deformation due to the relative movement between the vertical elements causing the damping material to be activated in shear. At least one of a first and second fuse member is connected to at least one of first and second ends of the damping element respectively. The fuse member is selected from a material, and otherwise sized and dimensioned to exhibit semi-rigid behavior when the damping element undergoes deformation due to loads below a predetermined load limit and to undergo deformation without substantially increasing the load in the fuse and in the damping element when loads exceed the predetermined load limit, such that the damping element is prevented from deforming beyond its predetermined deformation limit and therefore avoiding any occurrence of damage that would reduce its ability to provide damping to the structure. First and second connecting means are also provided for rigidly connecting the first and second fuse members to the first and second vertical elements, respectively.
