ICH RC 풍력타워 설계 (Ⅱ) : 높이별 단면 설계

Abstract

In the case of the current ICH RC wind power tower, the design method is getting quite complicated especially if it gets higher. So we, based on the previous basic cross section designs of ICH RC wind power tower, have mapped out the tower structures considering the correlation between their heights and diameters in this research. The cross section dimensions along the tower height were designed according to recommendations of ‘Design Criteria for Concrete design (2012).’ The cross sectional diameter of the wind tower decreases as its location is higher, and this decreasing diameter accorded with the decreasing bending moment. All designed cross sections and tower modules were evaluated of their bending moment capacities and compared with the design moment. The analysis results and comparisons showed that all designed modules satisfied their required capacities.structures considering the correlation between their heights and diameters in this research.
