摘要：
The structure system and performance-based design objectives of a resilient prefabricated prestressed steel frame with web friction energy-dissipation device were proposed for high-rise buildings. A four-story 3×5 span prototype structure was designed and a 0.75 scale substructure pseudo dynamic test was conducted. The results indicated that the resilient prefabricated prestressed steel frame has a good gap-opening and closing mechanism with self-centering and recovering the structural functions after earthquake; the loss of PT force is within 8% after test to reveal that PT strands, anchorage performance, and applying methods of PT force are reliable; the performance-based design objectives are realized with no gap-opening and damage under a frequent earthquake, with no damage of the main structure and the gap-opening energy-dissipated ability under a specified earthquake, with little damage and the normal serviceability under a rare earthquake, and with a little damage and the normal serviceability under a severe earthquake. © 2016, Editorial Office of Journal of Vibration and Shock.
