Using high-strength stirrups can form an effective constraint on high-strength concrete and greatly improve the deformation capacity,which above lay the foundation for high-strength longitudinal reinforcement used in the compressed member. This paper puts forward using high-strength steel bars( above 500 MPa) as longitudinal reinforcement of high-strength concrete column confined by high-strength stirrups. At first,the finite element model results were compared with the test results under the same parameters,and the accuracy of the model was verified. Then,the influence of the stirrup spacing and longitudinal reinforcement ratio on longitudinal reinforcement stress level and concrete strength were analyzed by using the finite element method. The results show that high-strength longitudinal reinforcement will play a good role in the member with reasonable stirrup spacing. Finally,the relationship between the strength of longitudinal reinforcement and bearing capacity of the member were discussed. The results provide a reference for theory research and application of high-strength longitudinal reinforcement used in confined concrete column.
