摘要:

采用试验与数值模拟相结合的方法,研究了钢骨架增强聚乙烯(SRPE)管约束玻璃纤维增强塑料(GFRP)海砂混凝土柱的力学性能和受力机理。通过24个轴压短柱试验,研究SRPE管钢丝体积配箍率、混凝土强度和GFRP箍筋间距等参数对组合柱力学性能的影响规律; 在确定合理材料本构模型的基础上,运用ABAQUS有限元软件进行数值模拟和参数分析。结果表明:在试验参数范围内组合柱虽均发生剪切破坏,但仍具有较好的延性,说明SRPE管和GFRP箍筋对海砂混凝土形成了良好的约束效应; 有限元数值参数分析结果表明,提高环向钢丝体积配箍率能显著提升峰值承载力、剩余承载力和延性,提高混凝土强度能显著提升峰值承载力、剩余承载力和弹性刚度,但延性明显降低,其他参数对组合柱力学性能的影响程度不显著; 基于参数分析结果,提出了组合柱轴压承载力和峰值应变简化计算式,可为类似工程实践提供参考。

Abstract:

The mechanical behavior and stress mechanism of glass fiber reinforced plastic(GFRP)-reinforced sea sand concrete-filled steel reinforced polyethylene(SRPE)tubular columns were studied by experiment and numerical simulation. Through 24 axial compression short column tests, the effects of SRPE pipe steel wire volume stirrup ratio, concrete strength and GFRP stirrup spacing on the mechanical behavior of the composite columns were studied. Based on the reasonable determination of the material constitutive model, ABAQUS finite element software was used for numerical simulation and parameter analysis. The results show that although the composite column fails in shear mode, it still has good ductility in the range of test parameters, which proves that the SRPE pipe and GFRP stirrup have a good confinement on the sea sand concrete. Finite element numerical parametric analysis shows that increasing the volume stirrup ratio of hoop steel wire can significantly improve the peak bearing capacity, residual bearing capacity and ductility. Increasing the strength of concrete can significantly improve the peak bearing capacity, residual bearing capacity and elastic stiffness, but the ductility is obviously reduced. The influence of other parameters on the mechanical behavior of composite columns is not significant. Based on the results of parameter analysis, the simplified calculation formulas of axial compression bearing capacity and ultimate strain of composite columns are proposed, which can provide reference for similar engineering practice.
