Abstract
An FRP DSCT (Fiber Reinforced Polymer Double-Skinned Composite Tubular) column was applied to a wind turbine tower and its bending performance was experimentally evaluated. A DSCT column is described as concrete is triaxially confined between two tubes and due to such confinement, it is highly stiff and it has high strength. In the study, two FRP DSCT column specimens, mono type (SP-1) and modular type (SP-2) were designed and quasi-static tests were carried out to investigate the bending strength of modular system for construction. As a result, final loads were taken as ultimate strengths for SP-1 and SP-2 when their lateral displacements were 154.25mm and 154.15mm. The Maximum loads applied on the specimens were 730.75kN and 517.445kN for SP-1 and SP-2 respectively. For the comparison of the test results, the modularized system showed lower results in displacements, loads and moments despite similar stiffness would be expected.en two tubes and due to such confinement, it is highly stiff and it has high strength.
