| 中文摘要:为研究钢框架-钢板剪力墙结构震后快速修复，通过统计既有试验结果，提出三级修复后使用性能指标，基于等效拉杆理论，建立有限元模型对指标进行验证，研究了结构在侧向荷载作用下塑性铰的出现顺序、层间位移角和结构应力发展情况等指标。结果表明：结构在一级修复后使用性能指标（1/220位移角）下，板墙轻微受损，对应修复方法指需要对板墙进行轻微修复。结构在二级修复后使用性能指标（1/110位移角）下，板墙几乎全截面进入塑性状态，需要考虑换板或增加加劲肋修复。结构在三级修复后使用性能指标（1/85位移角）下，板墙已经全部进入屈服，而且框架梁端也出现了塑性铰，此时不仅需要对板墙进行修复，还要考虑对框架进行修复。 |

| Abstract:In order to study the rapid repair of steel frame-steel plate shear wall structure after earthquake, through statistics of existing test results, three-level repair performance indicators are proposed. Based on the equivalent tie rod theory, a finite element model is established to verify the indicators, and the structural performance is studied. Indexes such as the appearance sequence of plastic hinges, the displacement angle between layers and the development of structural stress under lateral load. The results show that the slab wall is slightly damaged under the service performance index (1/220 displacement angle) after the first-level repair of the structure. The corresponding repair method refers to the need to slightly repair the slab wall. Under the service performance index (1/110 displacement angle) of the structure after the secondary repair, almost the full section of the slab wall enters the plastic state, and it is necessary to consider replacing the slab or adding stiffeners for repair. Under the service performance index (1/85 displacement angle) of the structure after the third-level repair, the slab wall has all entered yielding, and plastic hinges have also appeared at the frame beam end. At this time, not only the slab wall needs to be repaired, but also the frame is considered. Repair it. |
