dc.description.abstract | <jats:p>Owing to the recent expansion in sizes of wind turbines, the required height for the wind turbine tower is increasing. Therefore, new types of structures are needed to fulfill this requirement. In this study, a modular Internally Confined Hollow Reinforced Concrete (ICH RC) column was suggested for a wind power tower, and quasi-static test was performed to evaluate its bending performance. One single body specimen (SP-S) and two modular specimens (SP-MP, SP-MF) applying different connection methods were fabricated. The specimens were designed and manufactured while considering the numerical analysis and conditions of the testing laboratory. The test was conducted by controlling the displacement according to the drift ratio. The experimental results of moments, lateral loads, displacements, dissipation energy, ductility, etc. for each specimen were compared with those of numerical modeling. Consequently, plastic hinges were found at the bottom of the column and connection part for SP-S and modular specimens, respectively, which is due to the rigidity change at the connection of the modular specimens. Therefore, the result of energy dissipation was 40% higher in the case of the modular specimens than that of SP-S whereas the lateral force and moment in the case of the modular specimens were smaller than those of SP-S. In terms of displacement and energy ductility, modular specimens exhibited 50% higher results than those of SP-S. For the future work, it is necessary to enhance the performance of the connection part to apply the modular ICH RC structure to a wind turbine tower.</jats:p> | - |
