摘　　要：提出了一种四边连接圆形压痕钢板剪力墙,采用数值方法评估了其滞回性能,并与传统平钢板剪力墙和开圆孔钢板剪力墙的滞回性能进行了对比分析。此外,系统地研究了压痕孔径、压痕孔距、压痕深度、钢板厚度、钢材强度和压痕布置方式等参数对四边连接圆形压痕钢板剪力墙滞回性能的影响。分析结果表明:该压痕钢板剪力墙的抗侧刚度和水平承载力介于传统平钢板剪力墙与开圆孔钢板剪力墙的相应值之间,通过优化压痕设置,可实现其抗侧刚度与抗剪承载力的合理匹配。钢板厚度和钢材强度对压痕钢板剪力墙滞回性能影响显著,随着钢板厚度、钢材强度等级的增加,其水平承载力呈增大趋势。压痕孔径、压痕孔距和压痕深度对压痕钢板剪力墙滞回性能有一定影响,随着压痕孔径的增加,其水平承载能力呈下降趋势;随着压痕孔距的增加,其水平承载力与抗侧刚度呈增大趋势;随着压痕深度的增加,其水平承载力、抗侧刚度均呈降低趋势,但耗能能力呈增大趋势。压痕布置方式对压痕钢板剪力墙的滞回性能、抗侧刚度及水平承载力影响不显著。In this paper,a novel four-side connected steel plate shear wall(SPSW)with circular dents is proposed.The hysteretic behavior of the SPSW with circular dents was compared with that of plane SPSW and SPSW with circular hole through numerical simulation.The effects of dent diameter,dent spacing,dent depth,steel plate thickness,steel strength and dent arrangement type on its hysteretic behavior were systematically investigated.The results show that the lateral stiffness and strength of SPSW with circular dents are between those of plane SPSW and SPSW with circular holes.By optimizing dent arrangement,the reasonable matching of lateral stiffness and strength could be realized.The relative parameters,including steel plate thickness and steel strength,play a significant effect on the mechanical behavior of SPSW with circular dents,and the lateral strength of SPSW with circular dents increase with the increase of steel plate thickness and steel strength.The other parameters,such as dent diameter,dent distance,and dent depth,play a certain influence on its mechanical behavior.The lateral strength of SPSW with circular dents takes on the decreasing tendency with the increase of dent diameter,and the lateral stiffness and strength of SPSW with circular dents exhibit the increasing tendency with the increase of dent distance.The lateral stiffness and strength of SPSW with circular dents exhibit the decreasing tendency with the increase of dent depth,but its energy dissipation capacity increase.The effect of dent arrangement on its hysteretic behavior,lateral stiffness and strength is not obvious.
