摘要
为研究内置工字钢对钢管混凝土结构的加固作用,文中通过ABAQUS软件对钢管混凝土结构内部增设工字钢加固进行有限元模拟,研究工字钢对整体构件力学性能的提升;对构件组成部分进行应力分析,根据应力分布结果,提出相关建议;针对工字钢参数进行了分析,研究了不同的参数对轴压性能的影响,为此类构件试验和工程应用提供参考。
In order to study the reinforcement effect of the built-in I-beam on the CFST structure,the finite element simulation of the additional I-beam reinforcement inside the CFST structure was carried out by ABAQUS software,and the improvement of the mechanical properties of the I-beam on the overall component was studied.Stress analysis,according to the stress distribution results,put forward relevant recommendations.The parameters of the I-beam are analyzed,and the influence of different parameters of the I-beam on the axial compression performance is studied,which provides a reference for the test and engineering application of such components.
