摘　　要：为了进一步研究外包钢筋混凝土加固轴心受压柱的承载性能,通过ABAQUS有限元模拟对轴心受压柱的承载能力和初始负载进行了分析研究,并利用已有试验数据校核ABAQUS有限元模拟数据的准确性.研究表明,加固后原钢构件的刚度和承载能力都有较大的提升,极限承载力会随着原钢构件强度等级的增大而增大,随着初始负载的增大而减小.有限元模拟外包钢筋混凝土加固柱轴压受力分析结果与已有试验结果基本吻合.In order to further study the bearing capacity of the column under axial compression reinforced with outsourcing reinforced concrete,the bearing capacity and initial load of the column under axial compression were analyzed and studied by ABAQUS finite element simulation.The accuracy of the ABAQUS finite element simulation data was checked with the existing test data.Studies showed that the rigidity and bearing capacity of the original steel members are greatly improved after reinforcement.The ultimate bearing capacity will increase with the increase of the strength level of the original steel members,and decrease with the increase of the initial load.The finite element simulation results of the axial compression force analysis of the reinforced concrete-clad reinforced concrete column basically agree with the existing test results.
