摘要/Abstract

摘要： 为研究碳纤维增强聚合物-聚氯乙烯复合管(CFRP-PVC)约束珊瑚海水海砂混凝土(CSSC)柱的轴心受压性能,对6个试件进行轴心受压加载试验和有限元参数分析,重点研究了PVC管内、外表面CFRP层数和脱空缺陷对该组合柱轴压性能的影响。结果表明,CFRP-PVC管可以有效约束CSSC,使其处于三轴受压状态,当内、外壁均粘贴CFRP时可以有效减缓突然破坏的特征。相同情况下,管内壁粘贴1层CFRP时具有更好的延性和承载力,管外壁粘贴2层CFRP时约束应力提高系数高达121.5%,脱空缺陷仅对延性有显著影响。基于ABAQUS软件建立了CFRP-PVC约束CSSC柱有限元模型,准确还原了组合柱在轴向荷载作用下的破坏过程和CFRP损伤形态。当组合柱套箍系数小于0.3或长径比大于14.54时,荷载-位移曲线会失去强化段,提高外层CFRP层数会小幅提高强化段刚度。提出了适用于CFRP-PVC约束CSSC的承载力计算方法,误差为1.2%。

Abstract: To study the axial compression performance of coral aggregate seawater sea-sand concrete (CSSC) columns confined with carbon fiber reinforced polymer-polyvinyl chloride composite tube (CFRP-PVC), six specimens were subjected to axial compression load tests and finite element parameter analysis. The effects of the number of CFRP layers on inner and outer surfaces of PVC tube and void defects on the axial compression performance of composite column were studied. The results show that CFRP-PVC tube can effectively confine CSSC, placing it in a triaxial compression state. When CFRP is pasted on both the inner and outer wall with tube, it can effectively alleviate the characteristic of sudden failure. With one layer of CFRP pasted on the inner wall of PVC tube, better ductility and bearing capacity can be achieved under same conditions. With two layers of CFRP pasted on the outer wall of PVC tube, the coefficient of constraint stress increase is as high as 121.5%, and the void defects only have a significant impact on ductility. A finite element model of CSSC column confined with CFRP-PVC tube is established based on ABAQUS software, accurately restores the failure process and CFRP damage morphology of composite columns under axial load. Parameter analysis shows that when the confinement coefficient of composite column is less than 0.3 or the aspect ratio is greater than 14.54, the load-displacement curve will lose strengthening section. Increasing the number of outer CFRP layers will slightly increase the stiffness of strengthening section. A bearing capacity calculation method suitable for CSSC column confined with CFRP-PVC tube is proposed, with an error of 1.2%.

Key words: CFRP-PVC composite tube, coral aggregate seawater sea-sand concrete, axial compression performance, finite element analysis, bearing capacity calculation
