“…These observations indicate that the presence of the inner void does not compromise the performance of DSTCs; on the contrary, it has a beneficial influence on the axial deformation capacity of the composite system. Yu et al [44] In this section, the results of the present study and those available from the literature (i.e., Wong et al [27], Xie et al [41], Ozbakkaloglu and Louk Fanggi [37], Albitar [42], and Ding et al [43]) are compared with the predictions of the model by Yu et al [44], which is the only existing stress-strain model of DSTCs. Because the database contained specimens with ultimate strains established using two different measurement methods (i.e., fullheight LVDTs and mid-height LVTDs), the ultimate axial strains of the specimens in the database was scaled based on the relative …”

“…It can be seen from Figure 8 that the line connecting the peak points of each complete cyclic curve, which was the envelope line, was almost coincided with the monotonic compressive stress–strain curve. This conclusion had been confirmed by the uniaxial cyclic compression test [ 36 ], and the test results of actively confined cement concrete including steel tube infilled concrete [ 26 , 37 ], and passively confined concrete including various FRP confined concrete [ 19 , 38 ]. The experimental results showed this conclusion can also be applied to the actively confined GPC.…”

“…In previous studies, different unloading/reloading models [ 18 , 19 , 34 , 35 , 36 , 37 , 39 ] had been provided to predict the cyclic constitutive behavior of confined conventional cement concrete. In the following part, the Mander’s [ 34 ] and Lokuge’s [ 18 ] hysteretic constitutive model will be modified to obtain the predicted cyclic compressive stress–strain curve of confined GPC, and compare it with the cyclic stress–strain curve obtained from the experiment.…”

This paper investigated the performance of actively confined geopolymer concrete (GPC) through experiments. The mechanical properties of GPC under triaxial stress states were analyzed and discussed from the prospects of failure modes, axial peak stress and strain, monotonic and cyclic constitutive relationships. The experimental results demonstrated that the loading modes (monotonic loading and cyclic loading) had little effect on the failure mode and axial peak stress and strain. The improvement of the strength and ductility of GPC with the increase in confinement level was consistent with that of the conventional cement concrete while the strain enhancement of confined GPC was lower than that of confined conventional cement concrete at the same confinement level. The curves of the monotonic stress–strain and the envelop of cyclic compression were predicted through Mander’s model with good accuracy. The unloading/reloading models proposed by Lokuge were modified and the predicted cyclic hysteresis curves for actively confined GPC were in good agreement with the cyclic compression results. Findings from this study provide references for the application of geopolymer concrete.

“…Yu et al (2012) have performed some tests on behavior of circular hybrid DSTCs under cyclic axial compression, and the test results show that hybrid DSTCs are very ductile under cyclic axial compression. Furthermore, Albitar et al (2015) conducted a test about the cyclic axial compressive behaviour of DSTCs infilled with high-strength concrete, and the experimental results show that both normal and high-strength concrete DSTCs exhibited a highly ductile behavior under cyclic axial compression.…”

This paper presents an experimental study on the cyclic axial compressive behavior of FRP-concrete-steel hybrid double-skin tubular columns. The square column specimens were cast with an external Fiber Reinforced Polymer jackets, inner steel tube and concrete in between. The height of the columns was 500 mm and the side dimension was 150 mm. The effects of loading scheme, void ratio and diameter-thickness ratio on axial compression behavior were investigated. A total of eight columns were tested under monotonic and cyclic axial compression. The experimental results show that the effect of loading scheme on axial stress-strain envelope curve and the peak load were not significant, and the ultimate state of the square columns subjected to cyclic axial compression was very similar to that of specimens subjected to monotonic axial compression. Besides, compared with void ratio, the diameter-thickness ratio of the inner steel tube has significant influence on the peak load of the columns when subjected to cyclic axial compression.
