Abstract

A basic wind speed is a very crucial parameter used for calculating the wind loads on building structures. In Cambodia, the selection of the basic wind speed for the structural design remains uncertain due to insufficient fundamental studies on the wind characteristics associated with regional climate. This article aims to predict the basic wind speed in Siem Reap, Cambodia, as a case study based on datasets received from a meteorological station. The wind speeds were measured at Siem Reap airport in the form of hourly speed and then statically converted to 3-second gust speed using Gaussian distribution transformation. The extreme value distributions, such as Gumbel and Gringorten, were utilized to analyze the extreme wind speed in accordance with a return period. The results showed that with a return period of 50 and 700 years, the basic wind speed was found to be 35 m/s and 41 m/s, respectively. These results could provide an alternative selection for the estimation of wind load for the structural design of building in Siem Reap. However, additional studies on the assessment of the existing structures under the discovered wind speeds should be conducted in order to ensure the reliability of the results.
