摘要
GFRP管钢筋混凝土柱作为一种新型的组合结构构件,近来成为专家学者研究的热点。通过对不同中空率的GFRP管钢筋混凝土柱进行轴压性能试验和有限元数值模拟分析,研究不同中空率下混凝土柱的基本力学性能,结果表明:随着中空率的增大,GFRP管钢筋混凝土柱的承载力降低;在考虑发挥GFRP管钢筋混凝土组合柱的优点时,中空率取0.367~0.533区段,组合柱的力学性能较为合理。研究成果可为相关研究及工程实际应用提供参考。
As a new type of composite structural component, GFRP tube reinforced concrete column has become a hot research topic recently.The basic mechanical properties of concrete columns under different loading rates are studied by means of axial compression test and finite element analysis.The results show that,with the increase of the hollow ratio,the bearing capacity of GFRP tube reinforced concrete columns is decreased, and the mechanical properties of composite columns are reasonable when considering the advantages of GFRP tube reinforced concrete composite columns.The research results can provide reference for the related research and engineering application.
