Deformation enhanced assembly type double-yield-point buckling restrained brace device
A deformation enhanced assembly type double-yield-point buckling restrained brace device comprises an inner restraining device, an outer restraining device and an energy consumption device installed between the inner restraining device and the outer restraining device. After a strong earthquake, damage of the supporting device is concentrated on the energy consumption device, the inner restraining device and the outer restraining device are kept undamaged, and the repairing cost of the supporting device after the earthquake can be reduced. Besides, the supporting device has the double-order stress characteristic, that is, under the external force load, the first energy consumption core plate and the second energy consumption core plate enter the yield stage in sequence, self-adaptive control over the deformation mode of the structure under the strong earthquake is achieved, and the weak layer effect of the structure and the post-earthquake residual displacement response are restrained. In addition, the series stress relation between the first energy consumption core plate and the second energy consumption core plate is achieved through a special structure, and compared with an existing double-yield-point buckling restrained brace, the ultimate deformation capacity and the ultra-low cycle fatigue performance of the brace can be remarkably improved.
一种变形增强型装配式双屈服点屈曲约束支撑装置，包括内约束装置、外约束装置及安装于内约束装置和外约束装置之间的耗能装置。强震过后，该支撑装置的损伤集中于耗能装置，内约束装置和外约束装置保持无损，有利于降低支撑装置在震后的修复成本。另外，本支撑装置具有双阶受力特性，即在外力载荷下，第一耗能芯板和第二耗能芯板先后进入屈服阶段，实现对结构强震下变形模式的自适应控制，抑制结构的薄弱层效应和震后残余位移响应。此外，本发明通过特殊构造实现了第一耗能芯板和第二耗能芯板之间的串联受力关系，与现有双屈服点屈曲约束支撑相比，本发明可以使支撑极限变形能力和超低周疲劳性能显著提升。
