This invention refers to curtain walls capable of resisting the seismic forces of major earthquakes without breakage of their glass panes and without deformation or distortion of their structure. The above can be achieved through the operational separation of the curtain wall of each storey from those of adjacent storeys, by formation of a sliding line on the top of the windows (2.3), through the mutual hooks of suspension of the windows (6.3, 6.10) so that the displacement of the one storey to be independent from the others. The structure of the curtain wall of each storey confined only to the fixed part of the curtain wall of the storey and consists of the uprights (3.1), the sill-beam (3.2), the lintel-beam (3.3) and the attachments (3.4). There are no uprights in the region of windows. The uprights of the structure of curtain wall of each storey at no case are touching the glass panels. The interstorey drifts (.delta.) are in all directions absorbed by the suspension joints of the windows (7.5) and (7.6) and the angle profiles (10).

L'invention concerne des murs écrans capables de résister aux forces sismiques de tremblements de terre majeurs sans que leurs panneaux de verre se brisent et sans déformation ni distorsion de leur structure. Ceci peut être réalisé par la séparation fonctionnelle du mur écran de chaque étage de ceux des étages adjacents, en formant une ligne de coulissement sur le dessus des fenêtres (2.3), à travers les crochets réciproques de suspension des fenêtres (6.3, 6.10), de sorte que le déplacement d'un étage soit indépendant des autres. La structure du mur écran de chaque étage est confinée uniquement à la partie fixe du mur écran de l'étage, et comprend les montants (3.1), la traverse basse (3.2), le linteau (3.3) et les fixations (3.4). Il n'y a pas de montants dans la région des fenêtres. Les montants de la structure du mur écran de chaque étage n'entrent en aucun cas en contact avec les panneaux de verre. Les flottements entre étages (d) sont absorbés dans toutes les directions par les joints de suspension des fenêtres (7.5) et (7.6) et les profils d'angle (10).
