“…PVC materials exhibit some advantages such a low creep deformation, low diffusion for humidity, high electrical insulation, large ultimate strain, excellent corrosion resistance and durability, smooth surface, good mechanical stability, great consistency with other materials such as water, acids, and concrete, and easy machining, gluing, and cutting for fabrication versatility [58][59][60]. There-fore, FRP-PVC composite members offer both corrosion resistance of PVC and high strength capacity of FRP and they are promising materials for the application in special environments [5,[61][62][63].…”

“…There are numerous studies conducted regarding the compressive properties of FRP-PVC tubular columns. Several parameters, including the concrete characteristics and FRP-PVC properties, were investigated [8,56,[58][59][60][61][62][104][105][106][107][108][109][110][111][112][113][114]. In a study by Toutanji and Saafi [96], it was reported that the strength of PVC-FRP confined concrete (with h/D of 3) was high.…”

Mechanical behaviour of PVC-CFRP confined concrete column with RC beam joint subjected to axial load An experimental investigation on failure mode, ultimate strength, strain variation, and load-displacement curves of PVC-CFRP confined concrete column with reinforced concrete (RC) beam joint (PCRBJ) subjected to axial load was conducted in this study. Samples of a PVC confined concrete column with RC beam joint (PRBJ) and nine PCRBJs were designed using the principle of weak column and strong joint. A numerical analysis approach for convenient prediction of the load-displacement curve of specimen was proposed. It was established that the estimated values are in good agreement with test data.

“…So far, the mechanical properties of the PFCC column had been extensively studied, such as its static performance (Fakharifar and Chen, 2016; Ma et al, 2012; Toutanji and Saafi, 2002; Yu et al, 2015), seismic performance (Jiang et al, 2014b; Yu et al, 2018), and durability (Toutanji and Saafi, 2001), and a relatively complete research methodology was established. To promote the development of the PFCC from component level to structure level, the performance of the PFCC column-beam joint strengthened with an enlarged ring beam (Yu et al, 2019, 2020b) and core steel tube (Yu et al, 2020a) had been experimentally and theoretically investigated. In order to further enrich the connection form of the novel composite column and RC beam, referring to the existing joint connection methods, an enlarged joint strengthened with multi-layer steel meshes was proposed, as shown in Figure 1.…”

This paper presented a new joint core strengthened with multi-layer steel meshes for connecting the PVC-FRP Confined Concrete (PFCC) column and Reinforce Concrete (RC) beam. Seven specimens were tested under concentric compression and the effects of several parameters including the height, diameter of specimen and volume ratio of steel mesh on the compressive behaviors were investigated. Test results showed that all the reinforcement yielded successively and eventually the crushing of the concrete dominated the failures of specimens. The ultimate bearing capacity and ultimate equivalent axial strain decreased as the height of specimen increased, while they increased as the diameter of specimen or the volume ratio of steel mesh increased. The ultimate strains of all the reinforcement and concrete increased as the height of specimen increased while they decreased as the diameter of specimen or the volume ratio of steel mesh increased. Considering the influence of height of specimen, a modified formula for conveniently predicting the ultimate bearing capacity of the joint core strengthened with steel meshes was proposed based on the theory of confined concrete and superposition principle of multiple confinement. The predicted results were in good agreement with the experimental data. Additionally, an equivalent stress–strain relationship model of the joint core strengthened with steel meshes was suggested based on the experimental research. The predicted curves agreed well with the measured equivalent stress–strain curves. Moreover, a validated Finite Element (FE) model for the joint core strengthened with steel meshes was developed to conduct parametric studies, which broadened the available experimental results about the mechanical performances of the joint.
