摘要
为研究中空率对轴压中空GFRP管钢筋混凝土柱力学性能的影响,对不同中空率条件下的构件进行轴心抗压试验,并应用ANSYS软件,建立有限元模型进行仿真模拟,对得到的载荷-应变曲线和极限承载力进行分析.结果表明:随着中空率的增大,组合柱的承载力降低,GFRP管对核心混凝土的约束套箍作用减小,核心混凝土的厚度影响了GFRP管对核心混凝土的约束作用.所得成果可为相关研究及工程实际应用提供参考.
In order to study the effect of hollow rate to performance of GFRP reinforced concrete columns under axial compression, this paper analyzes the load-strain curves and ultimate bearing capacities of the composite columns based on axial compression test on columns with different kinds of hollow ratio and the establishment of the finite element models by ANSYS. The result shows that with the improvement of the hollow rate, the bearing capacity is increasing, however, the confinement effect by the GFRP tube on the core concrete is reducing which has no linear relation. The thickness of core concrete influence the constraint of GFRP tube to core concrete. The results can provide references for related research and engineering application.
