Previous earthquake experiences have shown that conventional yielding dampers designed for an earthquake intensity cannot perform adequately at higher intensity levels. This paper addresses this issue by proposing a two-level yielding configuration for knee-braced steel frames having an innovative deformation-controlled ring damper (CRD). The proposed configuration includes a knee ele... https://www.spidertattooz.com/Airbus-CC-330-Husky-Aircraft-Government-of-Canada-330002-White-with-Blue-and-Red-Stripes-copyright-Macs-Series-1-400-Die/
