비정규분포 풍속에 따른 피크팩터에 관한 연구

Lately damage caused by typhoons and regional squall has been increasing. In addition, the construction of high-rise buildings in metropolitan and coastal cities is increasing. In the case of high-rise buildings when the typhoon occurred, acceleration of the building increases. The vibration of the building is directly related to serviceability problems of residents. The serviceability of the building is determined by the maximum acceleration of the building. Country-specific peak factor estimating equations, necessary to calculate the maximum acceleration of the structure, are assuming that wind speed is a gaussian distribution. However, typhoon and strong winds, etc. that have a direct impact on serviceability, are almost non-gaussian distribution. Eventually country-specific codes are calculating the maximum acceleration which does not reflect the typhoon and strong winds. The study was conducted over a number of comparison of maximum acceleration applied peak factor. Peak factor is divided into two, country-specific peak factor estimating equations and peak factor using fifty wind speed data of weather center. As a result, the study presents need to reflect wind speed of non-gaussian distribution in peak factor estimating equations of code.
