摘要

针对高层建筑，提出了腹板摩擦耗能的可恢复功能装配式预应力钢框架结构体系和性能化设计目标。并设计了一个3×5跨4层原型结构，进行了0.75倍缩尺的子结构拟动力加载试验。试验结果表明:装配式预应力钢框架具有良好的开口闭合机制，震后能够自动复位和恢复结构功能。试验结束后，钢绞线索力损失在8%以内，说明钢绞线、锚具性能和钢预应力的施加方法是可靠的。结构实现了“多遇地震无开口、无损伤，设防地震开口耗能且主体结构无损伤、罕遇地震结构损伤很小能正常使用，超罕遇地震主体结构损伤较小且仍能正常使用”的性能化设计目标。

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.
