对市售塑料管（PVC和ABS）填充混凝土芯进行了理论分析和实验测试。理论分析表明，混凝土芯和塑料管之间存在相互作用，混凝土芯的强度相应增加。在柱荷载作用下，塑料管的结构性能类似于螺旋钢筋的性能。塑料管使混凝土芯的强度增加了约3.2倍的管爆裂压力。细长比效应在达到20的值后降低柱容量。试验结果表明，塑料钢管混凝土柱具有良好的结构应用前景。
A theoretical analysis and experimental tests were conducted on commercially available plastic pipe (PVC and ABS) filled with a concrete core. The theoretical analysis implied an interaction between the concrete core and plastic pipe and a corresponding increase in strength of the concrete core. Under a column loading, the structural behavior of the plastic pipe was similar to the behavior of spiral reinforcement. The plastic pipe increased the strength of the concrete core approximately 3.2 times the pipe burst pressure. Slenderness ratio effects reduced the column capacity once they reached a value of 20. Test results show that concrete filled plastic pipe columns show considerable promise for structural applications.
