Title:
DOORS AND WINDOWS SYSTEM HAVING EARTHQUAKE-RESISTANT PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2011/158990
Kind Code:
A1
Abstract:
The present invention relates to a doors and windows system having earthquake-resistant performance. The present invention comprises: a main frame having two vertical frame members that are separated so as to be mutually parallel to each other, and an upper frame member and a lower frame member connected to the upper and lower end portions of the vertical frame members; a plurality of pillar members that are separated from the vertical frame members and arranged side by side thereto; a support beam, which is fixed to the end portions of the pillar members, extends horizontally, and has both end portions separated from the vertical frame members; and a damper, which is fixed between the support beam and the upper frame member, or between the support beam and the lower frame member, receives a horizontal load applied from the exterior, and is plastically-deformed when yielding to a horizontal load that is more than the tolerated horizontal load. The doors and windows system having earthquake-resistant performance of the present invention is plastically-deformed by a horizontal load, and in particular, the stress increases consistently and continuously during the plastic deformation, displaying stable hysteretic characteristics, and thereby maintains the stability of the doors and windows system until just before a rupture.
