摘要 提出了一种由外框架、内框架和阻尼墙构成的新型框架-阻尼框筒结构体系。分析了阻尼墙对结构体系的刚度和阻尼贡献,推导了相应理论公式;研发了高承载力阻尼墙,并通过2个足尺试件的低周往复加载试验论证了其高承载力和高耗能能力;设计制作了2个两层单跨1∶2缩尺子结构模型,通过低周往复加载试验研究了框架-阻尼框筒结构体系的抗震性能。结果表明,框架-阻尼框筒结构体系具有优异的抗震性能,可应用于超高层建筑。 A new frame-damping frame tube structural system consisting of outer frame, inner frame and damping wall was proposed. The contributions of the damping wall to the stiffness and damping of the structural system were analyzed, then the corresponding theoretical formulas were derived. A high bearing capacity damping wall was developed, the high bearing and energy dissipation capacity were demonstrated through low cyclic loading tests of two full-scale specimens. The seismic performance of the frame-damping frame tube structural system was studied through low cyclic loading tests of two 1-span, 2-story, 1/2 scale models. The results show that the frame-damping frame tube structural system has excellent seismic performance and can be applied to super high-rise buildings.
