Abstract

Vibration caused by wind can be a factor in reducing residential performance for building users. Although serviceability problems such as residential performance are not significantly related to a building’s structural safety, wind-caused vibration is a detail that architects should consider, as it is related to the quality of residential performance. Such vibration can be reduced by adjusting the vibration acceleration in the top floor. Therefore, we aimed to implement an optimal design where residential performance is heightened by reducing vibration acceleration and optimizing building weights. NSGA-II was used as the optimal design technique, although NSGA-II has the shortcoming that the time required for structural analysis increases as the design variable and computational quantities increase. To overcome such problems, a resizing technique was used in the algorithm.
