摘要 在以往研究的基础上,提出可恢复功能的中间柱型阻尼器预应力钢框架结构的设计方法,并给出详细的设计流程。按照该设计方法和流程设计了一个10层可恢复功能的中间柱型阻尼器预应力钢框架结构,并对其在8度小震和中震作用下的基底剪力、层间位移角、震后各层残余位移角及中间柱型阻尼器的滑移值进行分析。结果表明,经过性能化设计的中间柱型预应力钢框架能够满足多遇地震无开口、无损伤,设防地震开口耗能且主体结构无损伤的设计要求,具有更高的抗侧刚度、耗能能力和明显的自动复位优势,验证了该设计方法的可行性。 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 8 th 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.
