Abstract

The structure system and performance-based design object of resilient prefabricated prestressed steel frame with web friction dissipation device for high-rise buildings were put forward. Four-story 3×5 span prototype structure was design and the 0.75 scale substructure pseudo dynamic test was conducted. The results indicated that the resilient prefabricated prestressed steel frame had the good gap opening and closing mechanism, self-centering and recovering the structural function after the earthquake. The loss of PT force was limited to 8% after the test, indicating that the PT strands, anchorage performance, and the applying methods of PT force were reliable. The performance-based design object was achieved that there was no gap-opening and damage under the frequently earthquake, and the connection could dissipate energy by gap opening without damage under the design earthquake, little damage and serviceability under the rare earthquake, a little damage and serviceability under the severe earthquake.
