| Wind load is the important design load of flexible structure, and it is decisive sometimes, such as tall, big, slender, and long structures, etc. Wind resistance is the important subject matter in engineering structure. There is obvious random uncertainty in wind load and structure's design parameters, so it is a basic way in structure wind resistance design to study the wind load and the structure's wind-induced static or dynamic response from the probability point of view. Base on reliability theory and the domestic and international previous research works in the same field, some relevant works are further studied in wind engineering and the wind resistance design of tall building or high-rise structure. The major contents are summarized as follows:1. Briefly analyse the difficulty that determine the design wind speed value based on short-term records, introduce the artificial neural networks into wind speed value estimate based on short-term records, and provide a new method to determine the design wind speed value in the district that only have short-term records.2. Basic wind pressure is direct ratio to the basic wind speed value's square, so it is important to choose the probability distribution function and the analysis methods to determine the most dangerous and the maximum wind pressure (wind speed) with different probability base on original records. An improved method is brought forward using the extremum distribution to analyse the original records.3. Fundamental wind pressure is the basic data in structural wind resistance design, the fundamental wind pressure provided by the Building Loading Code is obtained under the "standard conditions". The actual building's site condition is not coincides with the "standard conditions" commonly. It needs corresponding conversion with the standard fundamental wind pressure to get the actual fundamental wind pressure. In this paper, the author firstly illustrate the fuzzyness of the wind exposure categories and ground roughness, and then introduce the idea of fuzzy mathematics to determine the wind exposure categories and ground roughness exponent of actual building structural site using the fuzzy comprehensive evaluation, and then to get the actual fundamental wind pressure.4. The effect of horizontal load mainly including the wind load and seismic action becomes larger and larger with the building height increases, and make it become the decisive factor in structure design. The horizontal load influence increase sharply with the structure height increases, and make the structure sidesway become the important control index. A method is put forward to analyse the displacement control reliability of tall building under some suppose.5. Wind influence on tall building (high-rise structure) includes security and applicability. It makes the tall building flexible more and more as more aspects, such as the height increases rapidly, the structure system improves, more and more gentlematerial application, etc., and wind affects more continually. So it makes the human comfortableness become the important factor and even more determinant. Based on the human comfort calculating model of Technical Specification for Steel Structure of Tall Buildings in China, the probability distribution model and statistic parameters of the maximum acceleration of the peak along-wind, across-wind were presented here. Stochastic reliability and fuzzyness reliability analysis models of tall buildings are advised in this paper based on some criteria for human comfortableness.6. The conventional probability confidence level calculation of building structure is based on the hypothesis that the nominal values are the genuine mean values of all used parameters. In fact, they may be very close to the mean values and they may be very discrepancy too. So the confidence level calculated by the book method only one mean value, and it needs to discuss the confidence interval calculation method of the confidence level under given degree of confidence, to give some con...
