FATIGUE DAMAGE EVALUATION OF WIND LOAD ACTING ON VERTICAL FINS ON WALLS OF HIGH-RISE BUILDING

Abstract

Vertical fins on walls of building are required wind resistant design because these components are exposed to outer air. Recently, buildings tend to high-rise and long-life. High-rise buildings are predicted to be exposed to strong wind, long-life buildings are predicted to be longer time of action of fluctuating wind. Therefore, the evaluation of the wind resistant design for fatigue safety on cyclic wind load in-service period is necessary for a building. This study performs to evaluation of fatigue damage of vertical fins on walls of high-rise building as the wind force coefficient range by wind tunnel experiment. As a result, the tendency of the wind force coefficient range is similar to the tendency of the fluctuating value of wind force coefficients. On the other hand, it is confirmed that these tendencies are locally different.
