An extreme typhoon wind speed probability distribution model based on meteorological station observation data and a typhoon wind speed design evaluation method

The invention belongs to the field of engineering structure wind resistance design, and particularly relates to an extreme value typhoon wind speed probability distribution model based on meteorological station observation data and a typhoon wind speed design evaluation method. The invention provides an extreme value typhoon wind speed probability distribution model based on meteorological stationobservation data and a typhoon wind speed design evaluation method, solves the problem that a wind speed value obtained through actual measurement deviates from a real value under a standard landformdue to landform change, and provides reliable basic data for typhoon wind speed design evaluation. A cross-domain threshold method and generalized Pareto distribution are adopted to establish an extreme value typhoon wind speed probability distribution model based on observation data of a meteorological station, so that limited actually-measured typhoon wind speed data are fully utilized; The influence of wind speed and w
