| 中文摘要: |
| 在钢板剪力墙结构(简称SPSW)基于能量的性态抗震设计中,需要合理计算有不同滞回特征构件的滞回耗能。为反映剪力墙板滞回曲线的捏缩特征,本文提出了过程捏缩系数及平均捏缩系数,给出了剪力墙板滞回耗能的计算方法。采用数值方法细致分析1榀梁柱刚接的单层、单跨钢板剪力墙结构的滞回性能及耗能能力,并设计了12榀梁柱铰接的单层、单跨SPSW试件,考察了跨高比及高厚比两个参数对剪力墙板滞回性能的影响,总结了捏缩系数的变化规律,提出了简化计算公式。 |

| Hysteretic energy of steel components with different hysteretic characters in steel plate shear wall (SPSW) need to be calculated reasonably using energy-based seismic design method.In order to reflect the pinching effect of hysteretic curve,the stage and average pinching parameter were proposed in this paper,and the simplified computing method of steel component hysteretic energy with different pinching characters was also suggested.An one-story steel plate shear wall with moment resisting steel frame was designed,and the hysteretic behavior and energy dissipation capacity were analyzed.A total of twelve one-bay,one-storey SPSW with pinned connections were designed,and the effects of the ratios of span to height and height to thickness on hysteretic behavior of steel infill wall were analyzed.The rule of pinching parameter was concluded,and simplified calculating formula was proposed. |
