“…Kent & Park (1971) proposed a model depending on their previous studies. Park et al (1982), Saatcioglu & Razvi (1992), Sheikh & Uzumeri (1980, Sheikh & Yeh (1990), Mander et al (1988), Ahmad & Shah (1982) and Chung et al (2002) were those who proposed stress-strain models depending on test results. Studies on high strength concrete are limited compared to ordinary concrete Mugurama et al (1983), Nagashima et al (1992, Galeota et al (1992), Hsu & Hsu (1994), Cusson & Paultre (1995), Yong et al (1988) and Fafitis & Shah (1985).…”

The effects of confinement reinforcement on the behaviour of high strength concrete columns are investigated for which prismatic experimental specimens were prepared. In the experiment specimens, four longitude reinforcement and confinement reinforcement were used. For each experiment, stress-strain relationship of concrete was obtained and compared with models proposed earlier. The results show that confinement reinforcement improved the ductility of high strength concrete. The ascending branch of stress-strain curves depended on the ratio of confinement reinforcement was similar to the modified Kent-Park model and the descending branch similar to the Nagashima model.

“…According to previous theoretical analysis and finite element simulation results, it is assumed that stress distribution of the core concrete of CFEST is described by mathematical model as shown in Figure 12 [17][18][19]. The shaded area is effective distribution zone of lateral pressure, which consists of the surrounded area by two parabola According to the parabola C 1 and the straight line Y 1 are tangent at A(m, n), simultaneous equations can be solved:…”

This paper presents theoretical analysis of concrete filled elliptical steel tube (CFEST) members under axial compression. The theoretical analysis presents the distribution rule of interaction between steel tube and core concrete for CFEST column, which is verified and compared with both experimental tests and finite element (FE) simulations. The assumption of effective confined zone distribution of core concrete is proposed and the influence of cross-section shape on the confinement effect is analyzed. A unified axial compressive strength formula and stability factor are obtained for CFEST columns based on existing formulas for concrete filled circular steel tube (CFCST) columns.

Background:Loads on most of reinforced and prestressed concrete structures, are triaxial. For the principled analysis and design of these structures, being aware of the concrete behavior under triaxial stress states is essential. Also studying the stress-strain curves under triaxial loads for nonlinear analysis and design of reinforced and prestressed concrete structures, is important. Method:In this study, for better comprehension of the behavior of confined concrete, the uniaxial and triaxial tests are performed on the cylindrical specimens and the relationship between axial stress, lateral confining stress, and uniaxial compressive strength, is calculated and compared to the proposed relationships of other researchers. Results and Conclusion:In addition, a comparison is made between the test results, the results of others in the literature and Attard [1] model.
