Abstract

Abstract The behavior of concrete-filled double-skin poly vinyl chloride (PVC) tubular columns confined by plain PVC sockets is studied in this research. The plastic pipes have been used with concrete as columns. PVC has several advantages as it is inexpensive, light weight for construction, and decrease in the time taken for construction. Thus it can be used as an alternative to metal in various applications in which the maintenance cost is increased and the corrosion is reduced. This study is an experimental work on four groups of composite hollow PVC columns, each group containing three different samples. The effects of several parameters are studied, including slenderness ratio, compactness ratio, compressive strength, and confinement ratio. The experimental results show that stiffness, strength, as well as the ductility of composite columns of different loadings were considerably influenced by all these parameters. An increase in loading carrying capacity by about 40.4% was noticed as slenderness ratio decreased from 20 to 12 and about 21.1% as compactness ratio decreased from 50 to 25. Besides, the rate of increase in load capacity was about 96.6% as compressive strength increased from 33 to 54 MPa. For the case of variation of confinement ratio from 25 to 75%, the increase in the axial load capacity was about 56.7%. The main benefit of this type of column is the interaction between PVC tube and concrete. Besides, restriction of concrete by tube results in the delay of local buckling so that the concrete strength is enlarged by the effect of confining provided by the tube.

普通PVC插座约束双层皮PVC管混凝土柱的结构性能

本文研究了双层皮聚氯乙烯（PVC）管柱在普通PVC插座约束下的受力性能。塑料管已与混凝土一起用作支柱。PVC具有几个优点，因为它价格低廉，施工重量轻，并且减少了施工时间。因此，在增加维护成本和减少腐蚀的各种应用中，它可以用作金属的替代品。本研究是在四组复合中空PVC柱上进行的实验工作，每组包含三个不同的样品。研究了长细比、压实度、抗压强度和约束比等参数对混凝土强度的影响。试验结果表明，这些参数对不同荷载作用下组合柱的刚度、强度和延性均有较大影响。当长细比从20降低到12时，承载能力增加了约40.4%，当压实比从50降低到25时，承载力增加了约21.1%。此外，随着抗压强度从33增加到54，承载能力的增加率约为96.6% MPa。在约束比从25%变化到75%的情况下，轴向承载力的增加约为56.7%。这种类型的柱的主要优点是PVC管和混凝土之间的相互作用。此外，管对混凝土的约束导致局部屈曲的延迟，从而使混凝土强度因管的约束作用而增大。
