Abstract: 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 (6) are in all directions absorbed by the suspension joints of the windows (7.5) and (7.

Abstract: A curtain wall of a predetermined height includes prefabricated glassed panels, and a frame. The frame has only horizontal beams into which the glassed panels are placed for supporting the glassed panels without continuous vertical beams existing along the height of the curtain wall on a building with multiple floors.
