Study on occupant comfort evaluation mode of tall buildings in wind excitation based on fuzzy probability method

摘要

Occupant comfort mode in wind-induced vibration was proposed and studied based on fuzzy probability method (FPM). First, the predictions of the comfort mode were compared with the studies of other researchers to verify the reliability of the method proposed in this paper. Second, vibration comfort of 4 types of buildings was investigated and assessed respectively with the proposed mode. Third, parameters of influencing the occupant comfort, such as coefficient of variation and membership function (MF), were discussed, and optimal results were found. Finally, application of the comfort mode was investigated with a true super tall building. This study shows that the FPM is a feasible and reliable way of establishing the occupant comfort mode, and good predictions can be obtained, especially for FPM with MF1 and MF2. The quantitative story and total comfort ratios can be evaluated effectively for tall buildings in wind excitation. The proposed occupant comfort mode based on FPM provides a new and reliable way of investigating the comfort ratio of tall buildings quantifying vibration comfort and guiding structural comfort design.
