Basic wind speed analysis and serviceability evaluation of tall reinforced concrete building subjected to wind and earthquake: a case study in Phnom Penh

this case study presents the analysis of basic wind speed and serviceability evaluation of tall rein-forced concrete buildings under wind and earthquake in Phnom Penh. The objectives are to examine the basic wind speed in Phnom Penh and to compare the serviceability with earthquakes. First, the wind data collection from Phnom Penh Airport was analyzed and converted to basic wind speed, and then applied to the tall reinforced concrete buildings. After that, the reinforced concrete building was considered to be subjected to both wind and earthquake loads. Therefore, the serviceability parameters such as drift and stability index can be evaluated. The result showed that the basic wind speed for a return period of 50 years and 700 years is 35.42m/s and 43.87m/s, respectively. The lateral drift due to seismic as found is greater than that due to wind but for the drift serviceability design of tall reinforced concrete buildings, wind load might be the dominant factor to be considered rather than earthquake.
