Abstract
In order to study the seismic performance of reinforced concrete columns with high-strength spiral stirrups,the finite element analysis software ABAQUS was used as the main research method,combined with the measured data of two existing specimens,and extended analysis was conducted on 9 specimens using axial compression ratio and shear span ratio variation parameters.The influence of each influencing parameter on the seismic performance of rectangular high-strength spiral stirrup reinforced concrete columns was explored.The research results indicate that the ABAQUS finite element model established has a high degree of consistency in failure morphology,hysteresis curve,and skeleton curve;The axial compression ratio and shear span ratio have a significant impact on the seismic performance of the specimen.When the axial compression ratio limit is between 0.4 and 0.6,the requirement of ductility greater than 3 can be met,and the ductility is best when the shear span ratio is around 4.5.关键词
