摘要:
连梁作为剪力墙结构中的抗震第一道防线,其承载力和耗能能力对整体结构的抗震性能有重要影响。本文提出在连梁中附设粘滞阻尼器,利用阻尼器发生竖向剪切变形而耗能。结合实际工程研究粘滞阻尼耗能连梁的性能,采用ETABS和PERFORM-3D软件对粘滞阻尼耗能连梁结构与传统连梁结构进行有限元模拟对比分析,并对粘滞阻尼耗能连梁的各项最优参数进行研究。结果表明:粘滞阻尼耗能连梁充分发挥耗能作用,整体结构具有良好的抗震性能,与传统连梁结构相比,主体结构的弹性耗能得到明显降低。平面布置方式、竖向布置方式、阻尼器参数的选取对附设粘滞阻尼耗能连梁的框架-核心筒结构减震效果影响较大,合理选择这些参数可以使耗能结构减震效果最优。
Abstract:
As the first anti-seismic line of shear wall structure, the bearing capacity and energy dissipation capacity of coupling beam have an important impact on the seismic performance of the whole structure. In this paper, a viscous damper is attached to the coupling beam to dissipate energy due to the vertical shear deformation of the damper. Combining with the actual engineering research on the performance of viscous damping energy dissipation coupling beam(VDEDCB), ETABS and PERFORM-3D software are used to carry out the finite element simulation and comparative analysis between the VDEDCB structure and the traditional coupling beam structure, and the optimal parameters of the VDEDCB are studied. The results show that:the VDEDCB gives full play to the energy dissipation effect, and the overall structure has good seismic performance. Compared with the traditional coupling beam structure, the elastic energy consumption of the main structure is significantly reduced. The plane layout, vertical layout and damper parameters have great influence on the seismic response of frame-core structure with VDEDCB. Reasonable selection of these parameters can make the seismic effect of energy dissipation structure optimal.
