［摘要］在以往研究的基礎上，提出可恢復功能的中間柱型阻尼器預應力鋼框架結(jié)構(gòu)的設計方法，并給出詳細的設計流程。按照該設計方法和流程設計了一個10層可恢復功能的中間柱型阻尼器預應力鋼框架結(jié)構(gòu)，并對其在8度小震和中震作用下的基底剪力、層間位移角、震后各層殘余位移角及中間柱型阻尼器的滑移值進行分析。結(jié)果表明，經(jīng)過性能化設計的中間柱型預應力鋼框架能夠滿足多遇地震無開口、無損傷，設防地震開口耗能且主體結(jié)構(gòu)無損傷的設計要求，具有更高的抗側(cè)剛度、耗能能力和明顯的自動復位優(yōu)勢，驗證了該設計方法的可行性。

Abstract:Based on the test and numerical simulation research, the design method of the resilient prestressed steel frame structure with intermediate column dampers was proposed with the detailed design process. Thereafter, according to this design method and design process, a 10-story resilient prestressed steel frame structure with intermediate column dampers was designed. Parameters of the structure under the frequent and fortification earthquakes with 8th degree of earthquake fortification intensity were analyzed, including the shear force of base, the interlayer displacement angle, the post-earthquake residual displacement angle of each layer and the slipping value of intermediate column dampers. Results show that the applicability of the design method is verified because prestressed steel frame structure with intermediate column dampers after performance-based design meet the design requirements of no gap opening and no damages under frequent earthquake, meanwhile the gap opening for energy dissipation and no damage to main structures under the fortification earthquake, and the structure has strong lateral stiffness, good energy dissipating capacity and evident automatic resilient advantage.
