| 摘要: |
| 为研究四边连接、两边连接及开竖缝薄钢板剪力墙的滞回性能并对其设计选型提出建议,利用ANSYS有限元软件对三类薄钢板剪力墙的滞回性能进行数值模拟研究,对比分析了三类薄钢板剪力墙在低周往复荷载作用下的初始刚度、峰值承载力、耗能性能以及延性．分析结果表明:三类薄钢板剪力墙均具有良好的延性和耗能能力;四边连接和两边连接薄钢板剪力墙的滞回曲线有一定程度的捏缩,但其初始刚度和峰值承载力较高,可用作高层或高烈度区的多层钢结构住宅的抗侧构件;开竖缝薄钢板剪力墙的滞回曲线呈饱满的梭形,但其初始刚度和峰值承载力较低,可用作低层或低烈度区的多层钢结构住宅的抗侧构件． |

| Abstract: |
| To study the hysteretic performance and lectotype suggestion of the thin steel plate shear walls with four-side connections, two-side connections and silts, the hysteretic performance of those thin steel plate shear walls were systematically investigated utilizing the ANSYS software package. Comparisons of the initial stiffness, peak load, ductility and energy dissipation capacity of those steel plate shear walls were carried out base on the numerical results. Results showed that those three types of steel plate shear walls had proper ductility and energy dissipation capacity. The hysteretic curves of the thin steel plate shear walls with four-side connections and two-side connections had pinch phenomenon, while their initial stiffness and peak load were relatively high. They could be used in the multistory steel structure residences in high intensive seismic region or high-rise steel structure residences. The hysteretic curves of the thin steel plate shear walls with silts exhibited plump loops, but its initial stiffness and peak load were low. This kind of shear walls could be applied on the multistory steel structure residences in low intensive seismic region or low-rise steel structure residences. |
