원자력 발전소 자연 습식 냉각탑의 기하형상에 따른 구조적 거동에 관한 전산해석 연구
2012
The shell of form-finding is most important in design procedure of the cooling tower, because the shape of the shell determines the sensitivity of dynamic behavior of the whole tower against wind excitation. The purpose of the study is the investigation of the influences of the geometric parameters of the cooling tower shell on the structural behavior. As a result, a hyperbolic rotational shell with the small radius overall will yield the shell geometry with a higher first natural frequency and thus a wind-insensitive structure. Linearly and nonlinearly numerical analysis are demonstrated influence of the shell-geometric parameters on structural behaviours. The results of this study may be informative for the form-finding of the cooling tower shell.
