“…The compressive stress-strain model for FRP confined concrete at ambient temperature proposed by Lam and Teng [19,20] has been modified in the current study to account for the high temperature deterioration of material properties using an elastic modulus for unconfined concrete at elevated temperature proposed by Anderberg and Thelandersson [16]. In applying Lam and Teng's [19,20] model, the average ratio of hoop rupture strain to ultimate axial tensile strain of the FRP material (i.e.…”

U.; Bisby, M. F.; Green, M. F.; Bénichou, N.; Kodur, V. K. R. strengthening systems at elevated temperatures, and the perceived susceptibility of these systems to fire continues to discourage their use in some applications. To begin to address this issue for the specific case of strengthening rectangular concrete columns with FRP wraps, an experimental and analytical study has been performed. An objective of the study is to develop validated computational models that can be used to perform parametric analyses and suggest design guidelines for these types of structural members. This paper presents the development and partial verification of a computational model that can simulate the structural behaviour of a short or slender, concentrically or eccentrically loaded, unwrapped or FRP wrapped column under both ambient and fire conditions. Results of initial analytical studies, including validation of the model using test data available in the literature, are presented.

“…In many engineering fields, the CFRP-metal composite tanks or tubes have been used widely, such as gas tank used in motor vehicle and pipeline system for transporting high pressure gas or liquid used in municipal engineering or chemical engineering. CFRP materials, as external jackets for the confinement of reinforced concrete columns, can enhance strength and ductility [3][4][5][6].…”

is paper presented a comparative study of concrete-filled steel tubular (CFST) stub columns with three different confinement types from carbon fiber reinforced polymer (CFRP): outer circular CFRP, inner circular CFRP, and outer square CFRP. e compressive mechanism and physical properties of the composite column were analyzed firstly aiming at investigating the confinement effect of CFRP. Ultimate axial bearing capacity of these three CFRP-confined CFST columns was calculated based on Unified eory of CFSTand elastoplastic limit equilibrium theory, respectively. Meanwhile, the corresponding tests are adopted to validate the feasibility of the two calculation models. rough data analysis, the study confirmed the ultimate strength calculation results of the limit equilibrium method were found to be more reliable and approximate to the test results than those of Unified eory of CFST. en axial bearing capacity of the pure CFSTcolumn was predicted to evaluate the bearing capacity enhancement ratio of the three types of composite columns. It was demonstrated that the averaged enhancement ratio is 16.4 percent, showing that CFRP-confined CFST columns had a broad engineering applicability. rough a comparative analysis, this study also confirmed that outer circular CFRP had the best confinement effect and outer square CFRP did better than inner circular CFRP. e confinement effect of CFRP increased with the decrease of concrete strength, and it was proportional with relative proportions of CFRP and steel under the same concrete strength.
