ICH RC 풍력타워 설계 (I): 터빈용량별 기본단면 설계

Abstract

Internally confined hollow reinforced concrete (ICH RC) wind power towers were designed for various turbines sizes. Their cross sections were designed to have equal diameters to those of general steel wind power towers corresponding 3.6MW and 5.0MW turbines. And also, the sections with the average diameter of 3.6MW and 5.0MW turbines were designed. For the determined diameters, several cross sections were designed for various hollow ratios. The designed sections were set to have almost equal longitudinal reinforcement ratios. The performance analyses for the designed cross sections were carried out and the analysis results showed that the ICH RC wind power tower had enough strength for the required design loads.and 5.0MW turbines.
