该文针对偏心支撑结构存在的不足,提出一种新型的框架支撑形式——耗能器偏心支撑。该文采用1:3缩尺模型,进行了拟静力试验,并利用ANSYS有限元分析程序建立了有限元分析模型,将该新型耗能器偏心支撑结构进行了试验研究和理论分析比较。得出结论:该新型框架支撑形式不仅可以减少耗能梁段吸收的地震能量,也可以减小耗能梁段的破坏程度,从而减少震后修复工作量;并且具有很好的变形能力和足够的抗侧移能力。同时也给出了设计方法,并提出了改进措施。
Aiming at the deficiency of eccentric support structure, this paper proposes a new type of frame support - the eccentric support of energy dissipater. In this paper, a 1: 3 scale model was used to simulate the quasi-static test. The finite element analysis model was established by ANSYS finite element analysis program. The eccentric support structure of the new energy dissipater was experimentally studied and compared theoretically. It is concluded that the new type of frame support not only can reduce the seismic energy absorbed by the energy beam section, but also can reduce the damage extent of the energy dissipation beam section to reduce the post-earthquake repair workload; and has good deformability and sufficient Anti-lateral shift ability. At the same time, the design method is given and the improvement measures are put forward.
