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.　All　right　reserved.
