Hysteretic Behavior of Four-Side Connected Steel Plate Shear Walls with Circular Dents
摘要
Abstract
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.关键词
