Wind load on building surface is one of the main loads for structural design; scholars in this field have put forward some methods to calculate wind load, such as Simiu method and Kasperski method. Based on the basic theory of probability and the systematic analysis of the surrounding environment and turbulence, a random variable model for calculating wind load is established. According to the model, through the analysis of the relationship between guarantee rate and wind load, a numerical calculation method to calculate wind load is proposed based on extreme value analysis and polynomial fitting theory. To verify the performance of the algorithm, wind tunnel experiments were carried out to obtain a large number of first-hand measured data of high-rise building (Shanghai World Financial Center). Based on the measured data, the algorithm is simulated, and calculated results are analyzed, including wind pressure distribution on building and probability distribution of fluctuating wind pressure of some measuring points. The validity and accuracy of the proposed model and algorithm are verified by the comparative analysis and theoretical analysis of the calculation results.

基于相同保证率法的风荷载计算研究

建筑表面风荷载是结构设计的主要荷载之一；该领域的学者提出了一些计算风荷载的方法，如Simiu法和Kasperski法。基于概率的基本理论和对周围环境和湍流的系统分析，建立了计算风荷载的随机变量模型。根据该模型，通过对保证率与风荷载关系的分析，提出了一种基于极值分析和多项式拟合理论的风荷载数值计算方法。为了验证算法的性能，通过风洞实验获得了大量高层建筑（上海环球金融中心）的第一手实测数据。根据实测数据，对该算法进行了仿真，分析了计算结果，包括建筑物上的风压分布和部分测点风压波动的概率分布。通过计算结果的对比分析和理论分析，验证了所提模型和算法的有效性和准确性。
