钢筋混凝土剪力墙多竖杆模型的应用和讨论

Application of Multi-vertical-line-element Model of RC Walls and Discussion on IT

介绍了自编的框架-剪力墙非弹性动力反应分析程序,其中剪力墙采用多竖杆模型,框架梁、柱采用修正的单分量模型;并利用国外知名研究机构完成的 3层剪力墙结构模型的振动台试验结果,对该程序的剪力墙部分模型化的有效性进行了验证。结果表明,该程序能有效预测钢筋混凝土剪力墙在随机地震作用输入下的非弹性动力反应。最后对剪力墙模型化的一些关键问题进行了初步的讨论,提出了在单元弹簧组件恢复力模型方面进一步改进和完善多竖杆模型的基本思路。

The inelastic dynamic response analysis program for frame-shear wall structures developed by the authors is introduced firstly, in which the multi-vertical-line-element model was adopted for shear walls and the refined single-component model was used for beams and columns in frame.By analyzing three-story structural models tested in shaking-table in a famous foreign research institute, the validity of the modeling of shear wall in the program was verified. The analytical results indicate that the inelastic dynamic responseof shear walls under random ground motion input can be predicted effectively withthe program. Finally, with the preliminary discussion of some key points in modeling of shear wall, some suggestions areput forward for further improving and refining the multi-vertical-line-element model.
