Predictions of Wind Loads and Responses From Simulated Tropical Storm Passages

摘要

This paper presents the results of parallel analyses of tall building responses (structural loads, deflections, accelerations and local pressures) due to typhoon passages using a time-domain approach and a traditional analysis in which the tropical storm winds are represented by an equivalent probability distribution. The results show that the time-domain approach, which tracks the speed and wind direction signatures of particular storms, can result in larger predictions for responses which have a pronounced directional sensitivity. One consequence is that the benefits of wind directionality are reduced in regions where tropical storms are dominant.
