As an offshore wind power turbines is bigger, the slenderness of its supporting steel tower increases. And large slenderness makes the buckling failure probability of the wind power tower higher. To avoid this buckling problem, some researches for steel-concrete composite wind power are tried such as an internally confined hollow reinforced concrete (ICH RC) tower. In this research, the cross sections of ICH RC wind towers were designed and their bending moment were evaluated. And more, natural frequency analyses were carried out for the designed ICH RC wind power towers. The analysis results showed the designed sections satisfy the required safety conditions. |
