How to Provide Wind Information to Mitigate Strong Wind Disasters

Abstract

The phrase "a disaster you have never experienced" in the 2020 Typhoon No. 10 report is strange. In other words, past experiences differ depending on where the recipient of the information lives and the length of life, so it is not possible to convey the information accurately. To solve this problem, it is necessary to convey the expected wind speed in the form of frequency of occurrence.

This research proposes that the 100-year return period expected wind speed map and the 500-year return period expected wind speed map provided in the building load guideline are digitized as GIS polygon information, and the frequency of occurrence of a certain wind speed can be provided in the form of a return period map.
